[BUG] ox-odt file: links are not pointing to the real files (was: [BUG] ox-odt fails for org-id links (e.g., from org-roam v2) [9.5.2 (9.5.2-gfbff08 @ /home/moritz/.emacs.d/elpa/27.2/develop/org-9.5.2/)])

I am not sure which bug you are referring to.

I improved the code a bit, directly reusing file: link transcoder:
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=2f5e7103e59f06631e985d3dd39af21b5b7464ea

However, it does not change your observed behaviour.

I also tried the following Org file, and it looks like something is wrong
about file: link export in ox-odt. Even file: links have the erroneous
document path.

Probably, href=file.org is treated as a link to resource packed inside
.odt file.
I tried to look through
https://www.w3.org/TR/2001/REC-xlink-20010627/#link-locators, but I
cannot see any obvious correct way to link to external files from odt.
May someone more familiar with ODT schema take a look?
