I'm out of my depth here.  At the W3C AC meeting in Edinburgh, last 
year, I understood Henry to be stating that something like:

   http://www.iptc.org/docs/newscodes.html#123456

is not legal, as "123456" is an illegal fragment identifier.  It may
be that the resulting XML document is legal, but that the use in 
(X)HTML is illegal?
