Yes, in fact, in the XML working group, we're investigating
similar mechanisms. See[1]:

[1] Extensible Markup Language (XML):
                Part 2. Hypertext Links
W3C Working Draft March-31-97
5.3 TEI Extended Pointers
http://www.w3.org/pub/WWW/TR/WD-xml-link#sec5.3

Using that sort of thing, I would suggest

scheme://path.to.server/path/to/file.typ#pattern(I%20told%20you%20so)

Hmmm... the PATTERN keyword[2] seems to be part of the TEI
extended pointer syntax that isn't in xml-link --
at least not yet!

Whether support for XML mechanisms migrates into HTML
user agents is an open question.

The relavent HTML working draft is at:
Hypertext Links in HTML
           W3C Working Draft 28-Mar-97
http://www.w3.org/pub/WWW/TR/WD-htmllink

To evaluate the W3C stragy for HTML and XML, stay tuned to:
W3C Activity: Hypertext Markup Language (HTML)

and
