{I'm not a member of the CPPA list, so they won't see this :}

According to the XML namespace standard [1], 
	The prefix xml is by definition bound to the namespace name
	http://www.w3.org/XML/1998/namespace.
So the declaration is not required, but it might not be illegal to have
it.  I suggest *not* putting it, since it would cause folks to look
twice and wonder if the prefix is being bound to it's non-default
value.  And it's easier to point buggy software to the URL that shows
them where they're non-compliant. :)

Also, according to the same spec [2]
	Prefixes beginning with the three-letter sequence x, m, l, in
	any case combination, are reserved for use by XML and
	XML-related specifications. 

It's not clear if defining The "xml" prefix to have its official value
is allowed. :)

Again, it would lead to some puzzled looks.  I would refer to the
official canonical location.
