+        "library", and "uuid" attrs. The value of the "library" attr must
+        correspond to the name of a "library" element. The name of the effect
+        element is indicative, only the value of the "uuid" element designates
+        the effect for the audio framework.  The uuid is the implementation
+        specific UUID as specified by the effect vendor. This is not the generic
+        effect type UUID.
+        For effect proxy implementations, SW and HW implementations of the effect
+        can be specified.
+        Example:
+        <effect name="name" library="lib" uuid="uuuu"/>
+        <effectProxy name="proxied" library="proxy" uuid="xxxx">
