As long as zh-TW usage or idioms don't diverge from PRC (resulting
in a need to distinguish the language variety per se in addition to
the orthography) this would work, though I really don't like it.  If we go
this route, I'd like the registration form to give the reference materials
for Tongyong pinyin and to spell out that it's that, rather than Hanyu
Pinyin, that's intended with these two prefixes.  But I'd prefer not
combining one Tibetan and two different Mandarin orthographies
(along with an unspecified number of orthogrphies of other languages?)
into a single language variant.

I have the same concern about potential divergence in zh-TW usage
from PRC usage with these.

The registration form should specify references for this orthography as well.

I'd prefer listing *only* the -Latn- prefixes.

Now, a question.  Consider bo-Latn-TW-pinyin.  Would that be  Tibetan
as used in Tiawan in an orthography that looks something like Hanyu Pinyin,
or Tibetan in an orthography that looks something like Tongyong pinyin?
