Supporting full XML parsing unless the DTD were very strict (possibly
with strict ordering of frames, and also possibly including offsets in
the format) might be prohibitive in some of the players.

As a note... I would guess the vast majority of mp3 players can
read/write 2.4 (because Apple does and that dominates the market).
Hoewver, Apple's implementation is bust for frames larger than 128
bytes.  Sigh.  And they also use some proprietary frames. Sigh.  And
they are not flagged as such.  Sigh.

2.4 can do that.

UGH! UTF-7 is pretty wretched to work with.
