+** Purpose: Provides a methods of representing imaginary fields
+** which are unique to serialization.  In this case, what we're
+** representing is the private members of parent classes.  We
+** aggregate the RuntimeFieldInfo associated with this member 
+** and return a managled form of the name.  The name that we
+** return is .parentname.fieldname
