This class uniquely defines Xref subentities within an OdDbDatabase instance.

Each OdDbXrefFullSubentPath object consists of a OdDbSubentId object, an ordered array of Object IDs, and an ordered array of entity handles. The SubentId consists the index and subentType of the object. The array of Object IDs, and the array of handles, define the path to the subentity from the outermost entity (in PaperSpace or ModelSpace) to the entity containing the subentity.
