	\deprecated Xml serialization is deprecated. An alternative serialization system is provided through USD Physics.

	In order to serialize a class to RepX both a PxSerializer and
	a PxRepXSerializer implementation are needed. 

	A repx Serializer provides the ability to capture a live
	object to a descriptor or static state and the ability to
	write that state out to a file.  Objects allocated
	by the Serializer using the allocator are freed when the
	collection itself is freed.
	SnRepXCoreSerializers.cpp implements a set of Serializers
	for the core PhysX types.

	\note Implementing a PxRepXSerializer is currently not practical without including the internal PhysXExtension header "SnRepXSerializerImpl.h".
