Presumably because it is invalid according to the DTD specified.

The DTD indeed contains the following definition:
<!ENTITY % lang.attrib
"xml:lang %LanguageCode.datatype; #IMPLIED
lang %LanguageCode.datatype; #IMPLIED"

It's just an entity declaration, so we would need to track down how it
is used. The XHTML modularization is a relatively simple concept, but it
gets rather messy in practice.

The DTD mentioned is dated 26-Jun-2009. If it has a bug, perhaps it
hasn't been noticed, since the DTD is used so little. The DTD at
http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd
is newer and does not have this problem.
