//		This is required because when mapping from a reference
//		property value we may encounter nested references within
//		the object path.  Unfortunately the object path syntax
//		is such that we cannot be certain whether a key value
//		represents a reference or a string, datetime or char
//		property.  (This is because a textual object path does
//		not contain as much information as its XML equivalent.)
//
//		This function performs a heuristic test on the value to
//		determine whether it is a reference.
