I'm working on doing this for HTML as well.  Since the XML might include 
comments (particularly while it's an I-D), and I want to embed this *in* a 
comment, I was thinking about base64-encoding.  I see the usefulness of 
the XML being more easily-discovered, however, so what about turning the 
XML comment markers from "<!--" to "<!- -"?  Most of the other hacks I've 
thought of would require &lt;-escaping the XML, which would be worse than 
base64.
