//  Interop Provider - This provider services those classes from the
//  DMTF Interop schema association with the CIMOM itself
//
//  This provider services the following classes:
//      CIMObjectManager
//      CIM_ObjectManagerCommunicationMechanism
//      CIM_CIMXMLCommunicationMechanism
//      CIM_ProtocolAdapter  (Note: Removed because deprecated class in cim 2.9)
//      CIM_Namespace -- Only creates are allowed directly against this class.
//              This allows the publice class CIM_Namespace to be used to
//              create namespaces.  Modifies, deletes must use the returned
//              paths. Enumerates references, etc. all use hiearchy.
//              NOTE: Changes the class to PG_Namespace and returns that
//              objectpath
//
//      PG_Namespace - Pegasus particular subclass of CIM_Namespace that
//      add the parameters for shared namespaces
//
//      PG_CIMXMLCommunicationMechanism - Pegasus subclass of 
//      CIM_CIMXMLCommunicationMechanism that adds support for passing
//      additional communication parameters (ie. port, https vs. http, etc.)
//   
//      It also services the Interop associations tied to these classes
//      including:
//      CIM_NamespaceInManager
//      ...
//      Interop forces all creates to the PEGASUS_NAMESPACENAME_INTEROP 
//      namespace. There is a test on each operation that returns 
//      the Invalid Class CIMDError
//      This is a control provider and as such uses the Tracer functions
//      for data and function traces.  Since we do not expect high volume
//      use we added a number of traces to help diagnostics.
///////////////////////////////////////////////////////////////////////////////
/* TODO LIST:
    1. Finish the association functions

    2. UUID generation should become a system function since it will be used
       by many providers, etc. as part of id generation.

    3. Review the key parameters on create, etc. to be sort out which are
       required from user and which we can supply.  I think we are asking too
       much of the user right now.
