Because namespace prefixes can appear in element or attribute content, the
system can't tell whether a namespace is used or not.
In fact I've seen XML vocabularies (the Unicode LDML [1] is an example)
where a namespace declaration is required to appear on an element even
though it the namespace prefix is not used in that element or any of its
attributes.
