The dvi(xdv)-output isn't so much of a problem for tagging (but it
is not much tested). The main accessibility problem with xetex are
the missing support for real space chars. If you can't separate
words with real spaces accessibility is not given (if you write in a
language where spaces matters ...).

The second problem (that it shares with pdftex) is that it is not
possible to mark up correctly hyphens from hyphenation.

And naturally (again shared with pdftex) you can't produce proper
mathml ... and that affect all languages.
