   *===============================================================================
  
     -   Handle inheritance in all instance operations.      -   Clean up exceptions.
  
     -   Double check that all these operations work across protocol.      -   Resolve redundancy in which the namespace is passed to certain methods
           (getClass) and the CIMReference itself may contain a namespace arguent.
  
     -   Check that they have keys during validation.      -   Implement consistency and constraint checking on classes and instances.
  
 -   Associations:      -   Implement filtering (using includeQualifiers, localOnly, etc.)
  
     -   Implement CIMRepository::referencesOf()      -   Consider eliminating const CIM element classes.

 -   Exceptions:      -   Fix bug with cimserver.exe causing it to fail to start without te
           "-l" option.
  
     -   Force __FILE__ and __LINE__ argument on every usage of CIMException.      -   Resolve whether the backslash should be permitted in namespaces.
  
     -   Clean up and consolidate exception classes.      -   Create CIMOMContext (interface to CIMOM used b the provider).
   
     -   Propagate underlying error messages across the CIM protocol.

     -   Validate arguments to CIMReference compound constructor and modifiers.      -   Define Encoding module interface.
         (namespaces, hosts, classnames, and keybindings)  
  
     -   Be sure that escape sequences are handled inside of object names. For      -   Develop XMLEncodings module.
         example:  
  
             X.key1="Hello \"You\""      -   Develop BinaryEncodings module.
  
 -   Protocol:      -   Develop MOFEncodings module.
  
     -   Improve protocol tracing to show messages in both directions.      -   Employ BinaryEncodings module in repository (reduce disk usage).
  
     -   The TCPChannel::writeN() method blocks when the client and server      -   Combine repository instances, classes, and qualifiers  into their
         are in the same process. That is because the client cannot read          respective files (to reduce the number of files).
         anything as long as writeN() is blocked on a synchronous write.  
  
     -   Figure out how to handle getProperty() return type.      -   Employ an efficient indexing scheme in repository (B-trees or hashing).
  
     -   Provide ACE Channel implementation (for porting purposes)?      -   Develop module manager: interface, lookup scheme, and loading scheme.
  
     -   Handle PARAMETER.REFARRAY in Procotol?      -   Package Encodings classes as a module.
  
     -   Ignore extraneous XML elements (loosely valid).      -   Finalize repository assocations.

     -   Replace "std::something" with "STD(something)"      -   Design association provider infrastructure.
   
     -   Replace "using namespace std" with "USING_NAMESPACE_PEGASUS"  
   
 -   Aesthetics/Consistency/Usability:  
   
     -   Change getLength() and getSize() to just size(): "Brevity is the soul  
         of genius and of Lingerie".  
   
     -   Add methods to get objects by their names, in addition to index. For  
         example:  
  
             CIMProperty CIMClass::getProperty(const String& name);      -   Implement missing CIM protocol operations.
  
     -   Perform walkthrough to expose consistency problems.      -   Implement good observer module interface which allows different levels:
  
     -   Distinguish between private and public classes (otherwise, users may          -   Observation of client/CIMMOM connections/disconnection.
         come to depend on classes with unstable interfaces).

     -   Implement MOF provider registration scheme (according to the standard).      -   Change HTTP message id's to this format: "YYYY.MM.DD.HH.MM.SS.NNNNN".
  
 -   WBEM Query Language      -   GetInstances() and GetClasses() need to use iterators on
           provider and repository end. Otherwise, all classes or instance
           to be enumerated, must be sucked into memory.
  
     -   Find someone to work on standard.      -   Template bloat reduction.
  
     -   Implement leve-1 parser.      -   Need a tool to say which features are supported by a compiler.
