+   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: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
+             reserves for Jon Bosak in perpetuity the XML name

+  <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
