+ <!-- Overview.
+ This example config file was copy from existing one: frameworks/av/media/libeffects/data/
+ audio_effects.xml, with effect library names updated to AIDL libraries we currently have.
+
+ All "library" attributes in "effect" element must must match a "library" element with the
+ same value of the "name" attribute.
+ All "effect" attributes in "preprocess" and "postprocess" element must match an "effect"
+ element with the same value of the "name" attribute.
+
+ AIDL EffectFactory are relying on the "name" attribute in "effect" element to identify the
+ effect type, so it's necessary to have the mapping from name to effect type UUID. Make
+ sure to either use existing effect name as key of
+ ::android::hardware::audio::effect::kUuidNameTypeMap, or add a new {name, typeUUID} map
+ item to the kUuidNameTypeMap.
+
+ Existing audio_effects.xml should working without any change as long as:
+ 1. "path" attribute of "library" element matches with the actual effect library name.
+ 2. "name" attribute of "effect" and "effectProxy" element correctly added as key of
+ kUuidNameTypeMap, with value matches Identity.type in Descriptor.aidl.
+ 3. "uuid" attribute of "effect" element matches Identity.uuid in Descriptor.aidl.
+ 4. "uuid" attribute of "effectProxy" element matches Identity.proxy in Descriptor.aidl.

+ Each "effect" element must contain a "name", "library" and a "uuid" attribute.
+ The value of the "library" attribute must correspond to the name of one library element in
+ the "libraries" element.
+ The "name" attribute used to specific effect type, and should be mapping to a key of
+ aidl::android::hardware::audio::effect::kUuidNameTypeMap.
+ The "uuid" attribute is the implementation specific UUID as specified by the effect vendor.
+
+ Effect proxy can be supported with "effectProxy" element, each sub-element should contain
+ "library" and "uuid" attribute, all other attributes were ignored. Framework side use
+ result of IFactory.queryEffects() to decide which effect implementation should be part of
+ proxy and which not.
+
+ Only "name", "library", and "uuid" attributes in "effects" element are meaningful and
+ parsed out by EffectConfig class, all other attributes are ignored.
+ Only "name" and "uuid" attributes in "effectProxy" element are meaningful and parsed out
+ by EffectConfig class, all other attributes are ignored.
