//	This class is used internally as a source of CIM declarations.
//	It is passed to the _resolve() method of several classes (ClassDecl,
//	Method, Property, Reference, Qualifier). Methods are provided for
//	looking up class, qualifier, and instance declarations. This is
//	an abstract base class: implementations must be provided by derived
//	classes.
