Hi AUCTeX, The patchset for the new xref backend in tex-mode.el is still pending, but no matter what the eventual outcome of that I think we still need to have a complete set of AUCTeX modes included in `semantic-symref-filepattern-alist'. Without them we just get the cryptic message about customizing that variable when we try to use `xref-find-references'. Also, I don't know whether it was decided not to include the .tex extension where relevant, but this does mean that, without further intervention, `xref-find-references' won't search .tex files in any of the modes, even when you are actually searching from, say, a LaTeX-mode .tex file. This seems suboptimal to me. I attach a patch for your consideration.
