This also misses function items and other XDM 3 additions.

You could use any string if you declared it, ala MIME conventions, and
had a way to escape it, and a way to escape the escape.  SGML and XML
get that sadly wrong, and even microxml, as an XML subset, can't grok
&#ddd; used as part of an element name.

You need a string that cannot occur in the middle of a document (out of
band) or one that can be escaped (in band, future-proof but more work)
or content-length (hard to stream) or a chunked encoding (pain to decode
but I think more promising). Maybe EXI could be made to work?
