+   See http://www.w3.org/XML/1998/namespace.html and
+   http://www.w3.org/TR/REC-xml for information about this namespace.
+
+    This schema document describes the XML namespace, in a form
+    suitable for import by other schema documents.
+
+    Note that local names in this namespace are intended to be defined
+    only by the World Wide Web Consortium or its subgroups.  The
+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    id   (as an attribute name): denotes an attribute whose value
+         should be interpreted as if declared to be of type ID.
+         The xml:id specification is not yet a W3C Recommendation,
+         but this attribute is included here to facilitate experimentation
+         with the mechanisms it proposes.  Note that it is _not_ included
+         in the specialAttrs attribute group.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of
+         the original XML Working Group.  This name is reserved by
+         the following decision of the W3C XML Plenary and
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication
+             the W3C XML Plenary on this 10th day of February, 2000
+             reserves for Jon Bosak in perpetuity the XML name
+             xml:Father

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang, xml:space or xml:id
+        attributes on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2005/08/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>

+
+ <xs:annotation>
+  <xs:documentation>In keeping with the XML Schema WG's standard versioning
+   policy, this schema document will persist at
+   http://www.w3.org/2005/08/xml.xsd.
+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself, or with the XML namespace itself.  In other words, if the XML
+   Schema or XML namespaces change, the version of this document at
+   http://www.w3.org/2001/xml.xsd will change
+   accordingly; the version at
+   http://www.w3.org/2005/08/xml.xsd will not change.

+# parameter-framework configuration file XML Schemas
+
+These are W3C Schemas for the various configuration files.
+
+`xmllint` may be used to check for correctness, e.g:
+
+    xmllint --xinclude --noout --schema ParameterFrameworkConfiguration.xsd /path/to/your/ParameterFrameworkConfiguration.xml
+
+See `tools/xmlValidator` for a custom alternative tool.
+
+Only `ParameterFrameworkConfiguration.xsd`, `SystemClass.xsd`, `Subsystem.xsd` and
+`ConfigurableDomains.xsd` are relevant for use with xmllint: the others are
+included by these 4 XSDs.
+
+**You may refer to samples at
+<https://github.com/01org/parameter-framework-samples>.**
+
+## ParameterFrameworkConfiguration.xsd
+
+Schema for the **top-level configuration**.  It contains:
+
+- A reference to the `SystemClass` (aka StructureDescription) XML file (see
+  below);
+- The list of plugins (libraries) to be used. They may be split according to
+the folder they reside in. The `Folder` attribute can either be:
+
+    - an absolute path,
+    - a relative path (relative to the execution directory),
+    - empty.
+
+    In the first two cases, the runtime loader will be asked to explicitely load
+    the libraries found in the specified folder; in the last case (empty string)
+    the runtime loader will search for the library on its own (e.g. on Linux
+    distribution this is usually `/lib`, `/usr/lib` - see `man ld.so`)
+- Optionally, a reference to the `Settings`.
+
+Attributes of `ParameterFrameworkConfiguration` are:
+
+- The `SystemClass` name (for consistency check)
+- `TuningAllowed` (whether the parameter-framework listens for commands)
+- The `ServerPort` bind Address (PATH or TCP port) on which the parameter-framework listens if
+  `TuningAllowed=true`.
+
+## SystemClass.xsd
+
+Schema for the **SystemClass associated with the top-level configuration**.  It
+points to all the "Subsystem" files (see below).
+
+The `Name` attribute of the SystemClass must match the `SystemClass` attribute
+of the top-level configuration file. This name will be the first component of
+all parameters in it, i.e. if its name is "FooBar", its path is `/FooBar`. We
+will use this name in examples below.
+
+## Subsystem.xsd
+
+Schema for all **Subsystem files** (aka Structure files).  These files describe the
+content and structure of the system to be managed by the parameter-framework
+and also indicate which plugin is to be used.
+
+A Subsystem has the following attribute:
+
+- `Name` (self-explanatory); again it is the base component of all parameters
+  inside it; i.e. if its name is "Spam", its path is `/FooBar/Spam`;
+- `Type`, which indicates which SubsystemBuilder is to be used (each plugin can
+  declare one or more SubsystemBuilders); it may be defined as `Virtual`, in
+  which case, no plugin will be used and the parameters won't be synchronized.
+  This is useful for debugging but may also be used for the parameter-framework
+  to act as a configurable settings database;
+- `Mapping` (optional), defines a Mapping to be inherited by all Components in
+  the Subsystem.
+
+A Subsystem *must* contain:
+
+- A `ComponentLibrary`, which may include (using `<xi:include href="xyz.xml"/>`)
+  other files containing a `<ComponentLibrary>` or a `<ComponentTypeSet>` tag.
+- An `InstanceDefinition` which instantiates the parameters and may use
+  ComponentTypes defined in the ComponentLibrary.
+
+## ConfigurableDomains.xsd
+
+Schema for the ConfigurableDomains (aka Settings files).  These files contain
+the rules for applying values to parameters.
+
+Writing this file by hand is painful but it is not intended to be dealt
+with directly: instead, you may use the command-line interface (see
+`remote-process/README.md`) to set the settings and export the resulting
+Settings with the `getDomainsWithSettingsXML` command.

+   See http://www.w3.org/XML/1998/namespace.html and

+
+    This schema document describes the XML namespace, in a form
+    suitable for import by other schema documents.
+
+    Note that local names in this namespace are intended to be defined
+    only by the World Wide Web Consortium or its subgroups.  The
+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    id   (as an attribute name): denotes an attribute whose value
+         should be interpreted as if declared to be of type ID.
+         The xml:id specification is not yet a W3C Recommendation,
+         but this attribute is included here to facilitate experimentation
+         with the mechanisms it proposes.  Note that it is _not_ included
+         in the specialAttrs attribute group.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of
+         the original XML Working Group.  This name is reserved by
+         the following decision of the W3C XML Plenary and
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication
+             the W3C XML Plenary on this 10th day of February, 2000

+        attributes on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2005/08/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>

+  <xs:documentation>In keeping with the XML Schema WG's standard versioning

+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself, or with the XML namespace itself.  In other words, if the XML
+   Schema or XML namespaces change, the version of this document at

+     * Enrolls a user's face for a remote client, for example Android Auto.
+     *
+     * The HAL implementation is responsible for creating a secure communication
+     * channel and receiving the enrollment images from a mobile device with
+     * face authentication hardware.
+     *
+     * Note that the Hardware Authentication Token must be valid for the
+     * duration of enrollment and thus should be explicitly invalidated by a
+     * call to revokeChallenge() when enrollment is complete, to reduce the
+     * window of opportunity to re-use the challenge and HAT. For example,
+     * Settings calls generateChallenge() once to allow the user to enroll one
+     * or more faces or toggle secure settings without having to re-enter the
+     * PIN/pattern/password. Once the user completes the operation, Settings
+     * invokes revokeChallenge() to close the transaction. If the HAT is expired,
+     * the implementation must invoke onError with UNABLE_TO_PROCESS.
+     *
+     * Requirements for using this API:
+     * - Mobile devices MUST NOT delegate enrollment to another device by calling
+     * this API. This feature is intended only to allow enrollment on devices
+     * where it is impossible to enroll locally on the device.
+     * - The path MUST be protected by a secret key with rollback protection.
+     * - Synchronizing between devices MUST be accomplished by having both
+     * devices agree on a secret PIN entered by the user (similar to BT
+     * pairing procedure) and use a salted version of that PIN plus other secret
+     * to encrypt traffic.
+     * - All communication to/from the remote device MUST be encrypted and signed
+     * to prevent image injection and other man-in-the-middle type attacks.
+     * - generateChallenge() and revokeChallenge() MUST be implemented on both
+     * remote and local host (e.g. hash the result of the remote host with a
+     * local secret before responding to the API call) and any transmission of
+     * the challenge between hosts MUST be signed to prevent man-in-the-middle
+     * attacks.
+     * - In the event of a lost connection, the result of the last
+     * generateChallenge() MUST be invalidated and the process started over.
+     * - Both the remote and local host MUST honor the timeout and invalidate the
+     * challenge.
+     *
+     * This method triggers the IBiometricsFaceClientCallback#onEnrollResult()
+     * method.
+     *
+     * @param hat A valid Hardware Authentication Token, generated as a result
+     *     of a generateChallenge() challenge being wrapped by the gatekeeper
+     *     after a successful strong authentication request.
+     * @param timeoutSec A timeout in seconds, after which this enroll
+     *     attempt is cancelled. Note that the framework can continue
+     *     enrollment by calling this again with a valid HAT. This timeout is
+     *     expected to be used to limit power usage if the device becomes idle
+     *     during enrollment. The implementation is expected to send
+     *     ERROR_TIMEOUT if this happens.
+     * @param disabledFeatures A list of features to be disabled during
+     *     enrollment. Note that all features are enabled by default.
+     * @return status The status of this method call.

+     *     ItemsRequestBytes = #6.24(bstr .cbor ItemsRequest)

+/**
+ * IIdentityCredentialStore provides an interface to a secure store for user identity documents.
+ * This HAL is deliberately fairly general and abstract.  To the extent possible, specification of
+ * the message formats and semantics of communication with credential verification devices and
+ * issuing authorities (IAs) is out of scope for this HAL.  It provides the interface with secure
+ * storage but a credential-specific Android application will be required to implement the
+ * presentation and verification protocols and processes appropriate for the specific credential
+ * type.
+ *
+ * The design of this HAL makes few assumptions about the underlying secure hardware.  In particular
+ * it does not assume that the secure hardware has any storage beyond that needed for a persistent,
+ * hardware-bound AES-128 key.  However, its design allows the use of secure hardware that does have
+ * storage, specifically to enable "direct access".  Most often credentials will be accessed through
+ * this HAL and through the Android layers above it but that requires that the Android device be
+ * powered up and fully functional.  It is desirable to allow identity credential usage when the
+ * Android device's battery is too low to boot the Android operating system, so direct access to the
+ * secure hardware via NFC may allow data retrieval, if the secure hardware chooses to implement it.
+ * Definition of how data is retrieved in low power mode is explicitly out of scope for this HAL
+ * specification; it's up to the relevant identity credential standards to define.
+ *
+ * The 'default' HAL instance is explicitly not for direct access and the 'direct_access' HAL
+ * instance - if available - is for direct access. Applications are expected to provision their
+ * credential to both instances (and the contents may differ), not just one of them.
+ *
+ * Multiple credentials can be created.  Each credential comprises:
+ *
+ * - A document type, which is a UTF-8 string of at most 256 bytes.
+ *
+ * - A set of namespaces, which serve to disambiguate value names.  Namespaces are UTF-8 strings of
+ *   up to 256 bytes in length (most should be much shorter).  It is recommended that namespaces be
+ *   structured as reverse domain names so that IANA effectively serves as the namespace registrar.
+ *
+ * - For each namespase, a set of name/value pairs, each with an associated set of access control
+ *   profile IDs.  Names are UTF-8 strings of up to 256 bytes in length (most should be much
+ *   shorter).  Values stored must be encoed as valid CBOR (https://tools.ietf.org/html/rfc7049) and
+ *   the encoeded size is is limited to at most 512 KiB.
+ *
+ * - A set of access control profiles, each with a profile ID and a specification of the
+ *   conditions which satisfy the profile's requirements.
+ *
+ * - An asymmetric key pair which is used to authenticate the credential to the IA, called the
+ *   CredentialKey. This key is attested to by the secure hardware using Android Keystore
+ *   attestation (https://source.android.com/security/keystore/attestation). See
+ *   getAttestationCertificate() in the IWritableIdentityCredential for more information.
+ *
+ * - A set of zero or more named reader authentication public keys, which are used to authenticate
+ *   an authorized reader to the credential.
+ *
+ * - A set of named signing keys, which are used to sign collections of values and session
+ *   transcripts.
+ *
+ * Cryptographic notation:
+ *
+ * Throughout this HAL, cryptographic operations are specified in detail.  To avoid repeating the
+ * definition of the notation, it's specified here.  It is assumed that the reader is familiar with
+ * standard cryptographic algorithms and constructs.
+ *
+ *     AES-GCM-ENC(K, N, D, A) represents AES-GCM encryption with key 'K', nonce 'N', additional
+ *         authenticated data 'A' and data 'D'.  The nonce is usually specified as 'R', meaning 12
+ *         random bytes.  The nonce is always 12 bytes and is prepended to the ciphertext. The GCM
+ *         tag is 16 bytes, appended to the ciphertext.  AES-GCM-DEC with the same argument notation
+ *         represents the corresponding decryption operation.
+ *
+ *    ECDSA(K, D) represents ECDSA signing of data 'D' with key 'K'.
+ *
+ *    || represents concatenation
+ *
+ *    {} represents an empty input; 0 bytes of data.
+ *
+ *    HBK represents a device-unique, hardware-bound AES-128 key which exists only in secure
+ *        hardware, except for "test" credential stores (see createCredential(), below).  For test
+ *        stores, an all-zero value is used in place of the HBK.
+ *
+ * Data encoding notation:
+ *
+ * Various fields need to be encoded as precisely-specified byte arrays.  Where existing standards
+ * define appropriate encodings, those are used.  For example, X.509 certificates.  Where new
+ * encodings are needed, CBOR is used.  CBOR maps are described in CDDL notation
+ * (https://tools.ietf.org/html/draft-ietf-cbor-cddl-06).

+CppBor: A Modern C++ CBOR Parser and Generator
+==============================================
+
+CppBor provides a natural and easy-to-use syntax for constructing and
+parsing CBOR messages.  It does not (yet) support all features of
+CBOR, nor (yet) support validation against CDDL schemata, though both
+are planned.  CBOR features that aren't supported include:
+
+* Indefinite length values
+* Semantic tagging
+* Floating point
+
+CppBor requires C++-17.
+
+## CBOR representation
+
+CppBor represents CBOR data items as instances of the `Item` class or,
+more precisely, as instances of subclasses of `Item`, since `Item` is a
+pure interface.  The subclasses of `Item` correspond almost one-to-one
+with CBOR major types, and are named to match the CDDL names to which
+they correspond.  They are:
+
+* `Uint` corresponds to major type 0, and can hold unsigned integers
+  up through (2^64 - 1).
+* `Nint` corresponds to major type 1.  It can only hold values from -1
+  to -(2^63 - 1), since it's internal representation is an int64_t.
+  This can be fixed, but it seems unlikely that applications will need
+  the omitted range from -(2^63) to (2^64 - 1), since it's
+  inconvenient to represent them in many programming languages.
+* `Int` is an abstract base of `Uint` and `Nint` that facilitates
+  working with all signed integers representable with int64_t.
+* `Bstr` corresponds to major type 2, a byte string.
+* `Tstr` corresponds to major type 3, a text string.
+* `Array` corresponds to major type 4, an Array.  It holds a
+  variable-length array of `Item`s.
+* `Map` corresponds to major type 5, a Map.  It holds a
+  variable-length array of pairs of `Item`s.
+* `Simple` corresponds to major type 7.  It's an abstract class since
+  items require more specific type.
+* `Bool` is the only currently-implemented subclass of `Simple`.
+
+Note that major type 6, semantic tag, is not yet implemented.
+
+In practice, users of CppBor will rarely use most of these classes
+when generating CBOR encodings.  This is because CppBor provides
+straightforward conversions from the obvious normal C++ types.
+Specifically, the following conversions are provided in appropriate
+contexts:
+
+* Signed and unsigned integers convert to `Uint` or `Nint`, as
+  appropriate.
+* `std::string`, `std::string_view`, `const char*` and
+  `std::pair<char iterator, char iterator>` convert to `Tstr`.
+* `std::vector<uint8_t>`, `std::pair<uint8_t iterator, uint8_t
+  iterator>` and `std::pair<uint8_t*, size_t>` convert to `Bstr`.
+* `bool` converts to `Bool`.
+
+## CBOR generation
+
+### Complete tree generation
+
+The set of `encode` methods in `Item` provide the interface for
+producing encoded CBOR.  The basic process for "complete tree"
+generation (as opposed to "incremental" generation, which is discussed
+below) is to construct an `Item` which models the data to be encoded,
+and then call one of the `encode` methods, whichever is convenient for
+the encoding destination.  A trivial example:
+
+```
+cppbor::Uint val(0);
+std::vector<uint8_t> encoding = val.encode();
+```
+
+    It's relatively rare that single values are encoded as above.  More often, the
+    "root" data item will be an `Array` or `Map` which contains a more complex structure.For example
+    :
+
+``` using cppbor::Map;
+using cppbor::Array;
+
+std::vector<uint8_t> vec =  // ...
+    Map val("key1", Array(Map("key_a", 99 "key_b", vec), "foo"), "key2", true);
+std::vector<uint8_t> encoding = val.encode();
+```
+
+This creates a map with two entries, with `Tstr` keys "Outer1" and
+"Outer2", respectively.  The "Outer1" entry has as its value an
+`Array` containing a `Map` and a `Tstr`.  The "Outer2" entry has a
+`Bool` value.
+
+This example demonstrates how automatic conversion of C++ types to
+CppBor `Item` subclass instances is done.  Where the caller provides a
+C++ or C string, a `Tstr` entry is added.  Where the caller provides
+an integer literal or variable, a `Uint` or `Nint` is added, depending
+on whether the value is positive or negative.
+
+As an alternative, a more fluent-style API is provided for building up
+structures.  For example:
+
+```
+using cppbor::Map;
+using cppbor::Array;
+
+std::vector<uint8_t> vec =  // ...
+    Map val();
+val.add("key1", Array().add(Map().add("key_a", 99).add("key_b", vec)).add("foo")).add("key2", true);
+std::vector<uint8_t> encoding = val.encode();
+```
+
+    An advantage of this interface over the constructor -
+    based creation approach above is that it need not be done all at once
+        .The `add` methods return a reference to the object added to to allow calls to be chained,
+    but chaining is not necessary; calls can be made
+sequentially, as the data to add is available.
+
+#### `encode` methods
+
+There are several variations of `Item::encode`, all of which
+accomplish the same task but output the encoded data in different
+ways, and with somewhat different performance characteristics.  The
+provided options are:
+
+* `bool encode(uint8\_t** pos, const uint8\_t* end)` encodes into the
+  buffer referenced by the range [`*pos`, end).  `*pos` is moved.  If
+  the encoding runs out of buffer space before finishing, the method
+  returns false.  This is the most efficient way to encode, into an
+  already-allocated buffer.
+* `void encode(EncodeCallback encodeCallback)` calls `encodeCallback`
+  for each encoded byte.  It's the responsibility of the implementor
+  of the callback to behave safely in the event that the output buffer
+  (if applicable) is exhausted.  This is less efficient than the prior
+  method because it imposes an additional function call for each byte.
+* `template </*...*/> void encode(OutputIterator i)`
+  encodes into the provided iterator.  SFINAE ensures that the
+  template doesn't match for non-iterators.  The implementation
+  actually uses the callback-based method, plus has whatever overhead
+  the iterator adds.
+* `std::vector<uint8_t> encode()` creates a new std::vector, reserves
+  sufficient capacity to hold the encoding, and inserts the encoded
+  bytes with a std::pushback_iterator and the previous method.
+* `std::string toString()` does the same as the previous method, but
+  returns a string instead of a vector.
+
+### Incremental generation
+
+Incremental generation requires deeper understanding of CBOR, because
+the library can't do as much to ensure that the output is valid.  The
+basic tool for intcremental generation is the `encodeHeader`
+function.  There are two variations, one which writes into a buffer,
+and one which uses a callback.  Both simply write out the bytes of a
+header.  To construct the same map as in the above examples,
+incrementally, one might write:
+
+```
+using namespace cppbor;  // For example brevity
+
+std::vector encoding;
+auto iter = std::back_inserter(result);
+encodeHeader(MAP, 2 /* # of map entries */, iter);
+std::string s = "key1";
+encodeHeader(TSTR, s.size(), iter);
+std::copy(s.begin(), s.end(), iter);
+encodeHeader(ARRAY, 2 /* # of array entries */, iter);
+Map().add("key_a", 99).add("key_b", vec).encode(iter)
+s = "foo";
+encodeHeader(TSTR, foo.size(), iter);
+std::copy(s.begin(), s.end(), iter);
+s = "key2";
+encodeHeader(TSTR, foo.size(), iter);
+std::copy(s.begin(), s.end(), iter);
+encodeHeader(SIMPLE, TRUE, iter);
+```
+
+As the above example demonstrates, the styles can be mixed -- Note the
+creation and encoding of the inner Map using the fluent style.
+
+## Parsing
+
+CppBor also supports parsing of encoded CBOR data, with the same
+feature set as encoding.  There are two basic approaches to parsing,
+"full" and "stream"
+
+### Full parsing
+
+Full parsing means completely parsing a (possibly-compound) data
+item from a byte buffer.  The `parse` functions that do not take a
+`ParseClient` pointer do this.  They return a `ParseResult` which is a
+tuple of three values:
+
+* std::unique_ptr<Item> that points to the parsed item, or is nullptr
+  if there was a parse error.
+* const uint8_t* that points to the byte after the end of the decoded
+  item, or to the first unparseable byte in the event of an error.
+* std::string that is empty on success or contains an error message if
+  a parse error occurred.
+
+Assuming a successful parse, you can then use `Item::type()` to
+discover the type of the parsed item (e.g. MAP), and then use the
+appropriate `Item::as*()` method (e.g. `Item::asMap()`) to get a
+pointer to an interface which allows you to retrieve specific values.
+
+### Stream parsing
+
+Stream parsing is more complex, but more flexible.  To use
+StreamParsing, you must create your own subclass of `ParseClient` and
+call one of the `parse` functions that accepts it.  See the
+`ParseClient` methods docstrings for details.
+
+One unusual feature of stream parsing is that the `ParseClient`
+callback methods not only provide the parsed Item, but also pointers
+to the portion of the buffer that encode that Item.  This is useful
+if, for example, you want to find an element inside of a structure,
+and then copy the encoding of that sub-structure, without bothering to
+parse the rest.
+
+The full parser is implemented with the stream parser.
