The IsCompatible method verifies whether the referenced physical element may be contained by or inserted into the physical package. The return value should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred.  In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
