Greetings Apertiumers!
I've been reminded that derivational morphology exists, which throws a
wrench in my desire for full position-independent tags.
I've also been reminded that some repos have .udx files which specify
a conversion between Apertium tags and Universal Dependencies, but as
far as I know there isn't any documentation for this and I'm not even
sure where to find the script that processes them. Does anyone have
any further information on those files? I think it could be quite
useful to document and standardize them and adopt them more broadly.

Yes, most of our tools assume that tags are position independent, but
I've come across a handful of languages that treat some tags as
position dependent, and I was more hoping to make it official to make
it less likely that we run into issues with that.
Also, I have an idea for how to make a version of lt-proc -g that
accepts the tags in any order, which might be helpful for reducing
generation errors, though it may turn out to be too much of a slowdown
for production.

The UDX format was made by me for converting vislcg3 style treebanks
to UD-style ones.
It works mostly with longest-overlap set matching on the input. Some
challenges
are e.g. <prn><rel> vs. <n><rel>
<prn><rel> -> PRON PronType=Rel
<n><rel> -> NOUN NounType=Relat
I have a tonne of scripts that do it, one of which is:
https://github.com/ftyers/ud-scripts/blob/master/conllu-feats.py
I'd be happy to work on this topic as I find it interesting and there
are some substantial improvements that could be made over my existing
code.
