Well, I agree that verbatim pointers into PDFs would quickly turn into a
maintenance nightmare.  They aren't particularly convenient for users
either.  They are merely a low-tech approach that's trivial to realize.

One could think about (tool support for) formally checked hyperlinks
from ML sources into LaTeX (and other) documents.

Or one could look into help authoring tools, to see whether they can be
used to create proper context-sensitive help.  (Perhaps Jasmin has some
experience.)  Does jEdit offer useful functionality?  But that would be
a major move.

Kind regards,
