I think we *should* avoid them, but not *must*.

There may be exceptions (e.g. 'compact' in XOXO) which make sense.

AFAIK, the 'lang' attribute is the most broadly interoperably supported
(e.g. for the :lang() selector), and therefore from the perspective of
microformat principle of reusing widely interoperably implemented standards,
IMHO the 'lang' attribute is preferred, though there is a good argument to
be made for using *both* the lang and xml:lang attributes which *must* have
the same value.
