Well, in the words of a certain ex-president, "It depends on what the
meaning of the word 'is' is."
If by "is an xs:date" you simply mean is a string of characters that
satisfies the purely syntactic constraints specified in the W3C schema
spec for strings identified as xs:date, then I suppose it's possible for
an element to be an xs:date.
However, if you mean anything beyond that--for instance that a string of
characters is a certain day in history--then no, an element cannot be an
xs:date, merely be treated as one by a particular process.
