 Urgent  
 ======  
  
     -   Add CIMOM handle to provider interface.      -   Support for NULL property lists (in interface and protocol).
  
     -   Fix case sensitivity problems in repository (just add an _Open method      -   Rename tests (prepend "Test" to each test).
         that ignores the case of the file).  
  
     -   Add newly implemented repository operations to protocol and to      -   Fix bug with cimserver.exe causing it to fail to start without te
         dispatcher.          "-l" option.
  
     -   Change INVALID_CLASS exceptions to NOT_FOUND (they're wrong in      -   Resolve whether the backslash should be permitted in namespaces.
         Repository).  
  
     -   Add tracing of output HTTP messages.      -   Create CIMOMContext (interface to CIMOM used b the provider).
  
     -   Need CIMInstance::removeMethod() and CIMInstance::removeProperty().      -   Define Encoding module interface.
     -   Add a exists namespace operation under the repository stuff.  Maybe we  
     need more than this.  
  
 Topical To-Do List      -   Develop XMLEncodings module.
 ==================  
  
     -   Sun uses string message-ids. Pegasus uses integer.      -   Develop BinaryEncodings module.
         Sun uses 2000.5.12.... format. Changed Pegasus to  
         use string message-ids. DONE.  
  
     -   Some clients send '\n\n' to terminate HTTP headers.      -   Develop MOFEncodings module.
         We were only accepted '\r\n\r\n'. DONE.  
  
     -   Provide way of printing out command line options help from cimserver.      -   Employ BinaryEncodings module in repository (reduce disk usage).
  
     -   GetInstances() and GetClasses() need to use iterators on      -   Combine repository instances, classes, and qualifiers  into their
         provider and repository end. Otherwise, all classes or instance          respective files (to reduce the number of files).

     -   Use YACC on Linux.

     -   Implement CIMRepository::enumerateInstanceNames()      -   Implement missing CIM protocol operations.
  
     -   Handle inheritance in all instance operations.      -   Implement good observer module interface which allows different levels:
  
     -   Double check that all these operations work across protocol.          -   Observation of client/CIMMOM connections/disconnection.
  
     -   Check that they have keys during validation.          -   Observation of client/CIMOM communication.

     -   Clean up and consolidate exception classes.      -   CIM/HTTP Proxy for WMI.
  
     -   Propagate underlying error messages across the CIM protocol.      -   Web Server/Pegasus Integration (use HTTP protocol capabilities of

 -   References:      -   Add CIMRepository::namespaceExists() method.
  
     -   Validate arguments to CIMReference compound constructor and modifiers.      -   Change HTTP message id's to this format: "YYYY.MM.DD.HH.MM.SS.NNNNN".
         (namespaces, hosts, classnames, and keybindings)  
   
     -   Be sure that escape sequences are handled inside of object names. For  
         example:  
  
             X.key1="Hello \"You\""      -   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.
  
 -   Protocol:      -   Template bloat reduction.
  
     -   Improve protocol tracing to show messages in both directions.      -   Need a tool to say which features are supported by a compiler.
  
     -   The TCPChannel::writeN() method blocks when the client and server      -   Support unloading of dynamic libraries (presently only load() is
