Patch: Add more MDC support to XMLLayout and PatternLayout

           Summary: Patch: Add more MDC support to XMLLayout and
                    PatternLayout
           Product: Log4j
           Version: 1.3alpha
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Other
        AssignedTo: log4j-dev@jakarta.apache.org
        ReportedBy: paul.smith@lawlex.com.au


The attached zip file contains some patch files, and some additional files 
which extend some classes to support, or to extend support for MDC.

General Changes:

* XMLLayout now includes any MDC details by encoding in CDATA sections MDC 
Key/Value pairs.

* PatternLayout - the %X option used to require a secondary option to indicate 
which key to output.  This option is now no longer required, and if not 
specified, then ALL the MDC Key/Value pairs are output using a format similar 
to Hashtable.toString( e.g."{{key1,val1},{key2,val2}}")

Notes:
======
* The patch-dtd-mdcextensions.txt patches the log4j.dtd to allow an log4j:event 
to include MDC details.  This DTD change may not be entirely the way we want to 
go, and I would appreciate someone with XML experience looking over it a bit 
more thoroughly as I was not able to test the change as much as I would like.

* patch-src-*.txt - patches XMLLayout, PatternParser, and PatternLayout to 
enable MDC to appear, or to provide additional support.

* patch-test-*.txt - patches some Test case files to validate the source changes

* pattern.mdc.1.properties - a tests/input property file to configure a Test 
case

* patternLayout.mdc.1 - witness file for the PatternLayout change & test cases

* xmlLayout.mdc.* - witness files for the XMLLayout change & test cases

* Chainsaw has _NOT_ been modified to read in the MDC details from a standalone 
XML file.  My home computer was having a Blue Screen of Death everytime 
Chainsaw started up, so I was not able to even start on that change.  Hope to 
address that @ work during the week.
