&xsd;date has its own hyphenation rules. IIRC X3.30 hyphenation rules favour
omission so the closest thing to "2003-03-12" that could be considered
"American" is "20030312".
I agree that xml:lang has a place when such dates are inserted directly into
a literal were language is relevant, e.g.: "By 2003-03-12 this should be
finalized." is American and "By 2003-03-12 this should be finalised" is not.
However that is quite different from the case here (most importantly in the
cases where we have just a date it can be used by applications working with
any language without translation).
