Thanks. I searched unicode-ml and found PRC proposed
precomposed Tibetan charset: "BrdaRten" 956
characters
to BMP (U+A500-A8BB) on 2002. From the size of charset,
I suppose BrdaRten is "set A".

Yet I could not find the conclusion notes why it was
rejected, but from the discussion (sorry for google
cache), the uncomposed Tibetan charset was already
included (and it can cover whole of BrdaRten charset
'theoretically' - in the rejecters' viewpoint), it
might be the reason why new Tibetan charset was
rejected.

I was wrong in the point that PRC had proposed
the precomposed Tibetan charset, but I cannot
expect as they will be included in SMP etc.
So, still the classification of the charset is:

Thank you for notice. Their precomposed Tibetan
charset is developed by theirselves? They adopted
PRC's precomposed Tibetan charset A or B? If they
are published, I want to obtain a copy. I think,
there might be users who want to use precomposed
Tibetan charset without adoptation of whole PUA
codepoints definition in PRC.
