+                 - <routes/>: list of possible connections between input
+                   and output devices or between stream and devices.
+                   A <route/> is defined by a set of 3 attributes:

+                        -"sources": all the sources than can be connected to the sink via this route
+                 - <attachedDevices/>: permanently attached devices.
+                   The attachedDevices section is a list of devices names.
+                   Their names correspond to device names defined in "devicePorts" section.

+# This script is used to update audio policy configuration files
+# to comply with the updated audio_policy_configuration.xsd from V7.0.
+#
+# The main difference is the separator used in lists for attributes.
+# Since the XML Schema Definition standard only allows space to be
+# used as a separator (see https://www.w3.org/TR/xmlschema11-2/#list-datatypes)
+# the previous versions used a regular expression to validate lists
+# in attribute values. E.g. the channel masks were validated using
+# the following regexp: [_A-Z][_A-Z0-9]*(,[_A-Z][_A-Z0-9]*)*
+# This has an obvious drawback of missing typos in the config file.
+#
+# The V7.0 has shifted to defining most of the frequently changed
+# types in the XSD schema only. This allows for verifying all the values
+# in lists, but in order to comply with XML Schema requirements
+# list elements must be separated by space.
+#
+# Since the APM config files typically use include directives,
+# the script must be pointed to the main APM config file and will
+# take care all the included files automatically.
+# If the included file is a shared version from 'frameworks/av',
+# instead of updating it the script checks if there is a newer
+# version with the corresponding name suffix (e.g.
+# 'a2dp_audio_policy_configuration_7_0.xml') and updates the include
+# path instead.

+ * The HAL interface for biometric face authentication.
+ */
+interface IBiometricsFace extends @1.0::IBiometricsFace {
+    /**
+     * 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.
