Works for me.

Can the package that uses xref modify that string?  If so, we don't
need a single-fits-all phrase.

If we do need a single phrase, then how about "go to

Perhaps you could ask what issues need to be resolved for you to
understand the requirements.

If you can show me the complete Lisp, I can try that and return
feedback.

The recipe in #32 is clearly incomplete.  Not sure about 41.

Once again, if you can show a complete Lisp to try, I will.

Thanks.
