Chris:

Comments and replies are inline. Let me know if there are any other issues:

Sorry. I should have done this.
Martin: any chance we could update the w3c page with some examples of what
should be sent to this list? I think it might be helpful to have some
pointers to good example requests.

Thanks for the tip...

This section now reads:

Published specification:
 
    This media type registration is for XML bodies that
    conform to the DTD/Schema referenced in Appendix B and C and
    interpreted by the rules of the CCXML specification [1].

      [1] http://www.w3.org/tr/ccxml/

Good hint. I did not know that...

I will try to do that next time around...

Once again apologies...

Ok, this is what it will look like now:

Magic number(s):

There is no single initial octet sequence that is always present in CCXML
documents. This media type is expected to be handled by an XML processor, as
indicated by "+xml". XML processors may detect CCXML by its namespace URI,
http://www.w3.org/2002/09/ccxml

Is this ok with folks?
