//  DESCRIPTION:
//
//  If this object represents an embedded CIM object property value, then
//  as a result of changes to properties/qualifiers/path on this object it
//	is necessary to update the object in its parent.
//
//	This is to allow the following code to work:
//
//		Object.EmbeddedProperty.SimpleProperty = 3
//
//	i.e. so that the set to the value of SimpleProperty triggers an
//	automatic set of EmbeddedProperty to Object.
//
//  RETURN VALUES:
//		The underlying IWbemClassObject interface, or NULL.
//
//	NOTES:
//		If successful, the returned interface is AddRef'd; the caller is
//		responsible for release.

//
//  RETURN VALUES:
