I'd like to know whether it does! The editor of a journal I am associated
with has a strong distaste for citations in the form of URL's, on the basis
that (a) they tend to disappear, and (b) even if they stay around, the
contents often change. Is there any way an author can produce an acceptable
scholarly citation that references the XML standard? More importantly, is
there any guarantee that a researcher in 100 years' time will be able to
find a copy of the XML standard?
