        Gee!!!  I didn't understand what Subir was asking, nor figure
it out from looking at those two documements, and I still don't
understand it from this explanation.  Could somebody explain it again,
perhaps with explicit HREFs and BASEs, and what the resolved URLs were
hoped to be, but aren't with Lynx?

        Fragments are not part of the URL.  They're instructions
to the client about what to do with the document on receiving it,
just as parameters are not part of the path field in a URL, but
instructions to the client on how to make the request, or interpret
the reply if not overridden by headers from the server (which you
wouldn't get, for example, from an ftp server, and is why ftp URLs
support a ;type= parameter).
