OK. This is in fact a generic problem in HTML - consider most of the
things that the userJS
http://userjs.org/scripts/browser/enhancements/frameset-links does - links
like longdesc, the cite attribute from quotes, etc. Longdesc in particular
is important to get right, for accessibility (I am thinking about this
because I am blogging photos from a phone and want to share the results
with friends who are blind).
They are discoverable in the sense that they are in the DOM, which allows
user agents to work out something sensible - context menu (like iCab does
for most of these things) or a transformation on demand that shows the
links like Tarquin's script or an XSLT as an alternate stylesheet, or
exposing them in a particular user interface like JAWS does with its
propretary contexthelp attribute.
One of the difficulties is that many content providers don't want to
"clutter their page with help links" - something that I think is in fact a
bad design decision on their part, but nevertheless is a reality. (This is
related to the problems of design limitations that lead to things like
image replacement techniques...)
Anyway, having the ability to add a help link in the body, with particular
context-sensitivity (as discussed for including a link with rel="help" in
a form control label) is probably sufficient. I'll take that discussion
back to W3C's Protocols and Formats group (the part of WAI that deals with
review of specifications to ensure they enable accessibility) and see what
they think...
cheers and thanks - I think this discussion has helped me clarify some of
the issues too.
