 Urgent  
 ======  
  
     -   Add CIMOM handle to provider interface.      -   Revisit use of namespace v.s. objectName in all CIM operations.
  
     -   Fix case sensitivity problems in repository (just add an _Open method      -   What do we do when getInstance() is called and the nameSpace is
         that ignores the case of the file).          provided both as an argument and as part of the instance name?
  
     -   Add newly implemented repository operations to protocol and to      -   ReferenceNames should return classes not just instances?
         dispatcher.  
  
     -   Change INVALID_CLASS exceptions to NOT_FOUND (they're wrong in      -   Remove final const from const methods in non-const CIM element classes.
         Repository).  
  
     -   Add tracing of output HTTP messages.      -   Null vs. empty CIM/HTTP parameters.
  
     -   Need CIMInstance::removeMethod() and CIMInstance::removeProperty().      -   Resolve constness problems. (get rid or Const classes?)
     -   Add a exists namespace operation under the repository stuff.  Maybe we  
     need more than this.  
  
 Topical To-Do List      -   Change CIMReference to CIMObjectPath?
 ==================  
  
     -   Sun uses string message-ids. Pegasus uses integer.      -   Finish associations.
         Sun uses 2000.5.12.... format. Changed Pegasus to  
         use string message-ids. DONE.  
  
     -   Some clients send '\n\n' to terminate HTTP headers.      -   Provide CIMOM Context.
         We were only accepted '\r\n\r\n'. DONE.  
  
     -   Provide way of printing out command line options help from cimserver.      -   Complete conventions document.
  
     -   GetInstances() and GetClasses() need to use iterators on      -   The CIMServer.exe program should probably create the logs directory
         provider and repository end. Otherwise, all classes or instance          under PEGASUS_HOME.
         to be enumerated, must be sucked into memory.  
  
     -   Template bloat reduction.      -   Clean up exceptions.
  
     -   Use YACC on Linux.      -   Resolve redundancy in which the namespace is passed to certain methods
           (getClass) and the CIMReference itself may contain a namespace arguent.
  
     -   Need a tool to say which features are supported by a compiler.      -   Implement consistency and constraint checking on classes and instances.
  
     -   Support unloading of dynamic libraries (presently only load() is      -   Implement filtering (using includeQualifiers, localOnly, etc.)

           "-l" option.
  
     -   Implement CIMRepository::modifyInstance()      -   Resolve whether the backslash should be permitted in namespaces.

     -   Implement CIMRepository::referencesOf()      -   Combine repository instances, classes, and qualifiers  into their
           respective files (to reduce the number of files).
  
     -   Implement CIMRepository::associatorsOf()      -   Employ an efficient indexing scheme in repository (B-trees or hashing).
  
     -   Implement protocol stubs for these operations.      -   Develop module manager: interface, lookup scheme, and loading scheme.
  
 -   Exceptions:      -   Package Encodings classes as a module.
  
     -   Force __FILE__ and __LINE__ argument on every usage of CIMException.      -   Finalize repository assocations.
  
     -   Clean up and consolidate exception classes.      -   Add association CIM/HTTP operations.

     -   Be sure that escape sequences are handled inside of object names. For          -   Observation of client/CIMMOM connections/disconnection.
         example:  
  
             X.key1="Hello \"You\""          -   Observation of client/CIMOM communication.
  
 -   Protocol:          -   Observation of CIMOM/repository communication.
  
     -   Improve protocol tracing to show messages in both directions.          -   Observation of CIMOM/provider communication.
  
     -   The TCPChannel::writeN() method blocks when the client and server          -   Observation of CIMOM state transitions.
         are in the same process. That is because the client cannot read  
         anything as long as writeN() is blocked on a synchronous write.  
  
     -   Figure out how to handle getProperty() return type.      -   Pegasus providers for Sun WBEM Services.

 -   Aesthetics/Consistency/Usability:      -   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.
  
     -   Change getLength() and getSize() to just size(): "Brevity is the soul      -   Template bloat reduction.
         of genius and of Lingerie".
