This interface is implemented by elements that are able to do XMP serialization. Examples for such elements are #jifmux and #qtmux.
Applications can use this interface to configure which XMP schemas should be used when serializing tags into XMP. Schemas are represented by their names, a full list of the supported schemas can be obtained from gsttag.global.tagXmpListSchemas. By default, all schemas are used.
