It's not "my" reasoning. It's a consequence of sticking to the rules established
in ltru. However, there are crucial questions underlying both cases, for which
the respective answers may differ. The first group of questions is whether
Latgalian can *correctly* be tagged as "lav", whether Walliserdeutsch can
*correctly* be tagged as "de", and whether Walliserdeutsch can be *correctly*
tagged as "gsw". The second group of questions is whether there is anything
approaching a "standard" "lav", "de", or "gsw". In the last case, I'm pretty
sure the answer is "no such animal".
