Date: Sun, 17 Sep 2023 09:49:46 +0100

Hi Tassilo and Keita,

Thanks for the clarifications. If you look at the current patch to
tex-mode.el, there's one function call added to TeX-mode-hook, mainly
for my own testing purposes, but no matter what the final patch looks
like it should only similarly require a single function call in an
AUCTeX hook to activate the new xref code there, along with one in
tex-common-initialization for the in-tree modes. If and when all
parties are satisfied by the patch I'll certainly be in touch with you
to find out how you'd prefer to handle activating it (or not) in
AUCTeX. The current state of affairs is a convenience for me and for
anyone else who cares to test the code.

Thanks again,

David.
