I've looked at the latest XHTML spec from 2009-05-07. Referring to


In the I18N module, there are only two attributes listed: dir and
xml:lang. The note in the last paragraph says: "Finally, note that the
I18N collection only contains the xml:lang attribute unless the Bi-
directional Text Module module is selected." This is fine, but...


says (last paragraph):

"This specification also adds the lang attribute to the I18N attribute
collection as defined in [XHTMLMOD]. The lang attribute is defined in
[HTML4]. When this attribute and the xml:lang are specified on the
same element, the xml:lang takes precedence. When both lang and
xml:lang are specified on the same element, they SHOULD have the same

Is the 'lang' attribute deprecated? If it is not, it should be in the
I18N module as well. If it *is* deprecated,


is wrong, isn't it?

Well the latest "spec" so far is a "Proposed Edited Recommendation" that
in its introduction explicitly says (it) "integrates the lang attribute
to increase compatibility with User Agents and Assistive Technologies".
That way I don't believe the presence of the lang attribute is an error,
it is a deliberate change. Whether or not they intend to change the
module as well I don't know. You could join the relevant W3C mailing
list mentioned in the recommendation.
