Unfortunately, it isn't quite that simple.  HTML may have
DAML embedded in it, file suffixes are optional with most
servers, and tracking file suffixes is a never-ending
proposition.  The right longer-term solution is probably for
HyperDAML to act based on the MIME type, but we don't yet
have a DAML MIME type and the new W3C RDF Core Working Group
is just beginning to tackle that issue for RDF (with
suggestions like text/xml+rdf).

It would also be helpful if RDF had a means of
distinguishing references to other RDF instances from
arbitrary resources.  With DAML+OIL (March 2001), it may be
preferable to use xsd:uriReference DatatypeProperties for
such foreign references.

I like this idea!  Unfortunately, many DAML/RDF documents
don't use this, including (we should fix this)

A reasonable hack might be to only generate hyperdaml links
for references containing #fragments, but that doesn't help
in your case.
