That permits LTR or RTL, bot not an empty dir="", or
is it another SGML oddity I've never before heard of ?

Yes, my question was why the draft needs dir="" at all,
and if it also updates HTML and XHTML for the purposes
of ATOM. 

xml:lang="" in XML 1 turned out to be a major headache
for XHTML 1, because it is forced to mirror HTML 4.01
as good as possible, and an NMTOKEN cannot be empty.
