OK I found the MDC section in the manual and it looks to be what I
need *except* I cannot create XML style comments in the log file to
contain the MDC value.
If the pattern layout is :
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%m%n\<!-- %X{reqid} --\>%n"/>
</layout>
(and without the < and > quoted with the backslash)
I get this exception when the config is parsed :

Yet the API for PatternLayout specifies "You are free to insert any
literal text within the conversion pattern."
I can't use the XMLLayout because I don't want to create an XML
formatted log file, I just want to dump what I have (which happens to
be XML) to a file and append the XML comment to the end.
Any suggestions?
