Yes, and this is one of our really big outstanding serious
architectural problems.  It's really important for the 
workings of the web that an address such as 

http://example.com/foo#Chapter12

have well-defined semantics.  If foo turns out to be XML, 
this is hopelessly underdefined.  At various times James Clark
and I have both suggested that we just brutally hijack the 
attribute name "id" and assert that it is of DTD type ID.

Other ideas have included using xml:id or having a reserved
namespace http://w3.org/xmlid or some such; any attribute 
associated with it is of type ID.

This one isn't going to go away.  -Tim
