public class OutOfTypeSystemData
extends Object
This class is used by the XCASDeserializer to store feature structures that do not fit into the
 type system of the CAS it is deserializing into. This data can then be passed to the
 XCASSerializer, which will include it in the XCAS it produces. In this way consumers of an XCAS
 can safely ignore out-of-typesystem data without destroying it.
