There is a similar issue with xml:lang.

Some processors (e.g. early LotusXSL and others) did not have built-in
declarations for xml:lang.  But when you tried to give one, it required
a namespace declaration. And then it would say that declaring an
xml namespace was not allowed.

I think it is a sign of inadequate testing. Developers should check that
their products allow xml:lang in WF, valid and namespaced documents.
Even just putting xml:lang="en-US"  on one  element in a test file
should
expose  the problem.

The spec says "In valid documents, this attribute, like any other, must
be
declared if  it is used."
