I would say 'legal', but not 'perfectly legal'! I think it's a case that if
we were applying regular laws, lawyers could make a lot of money out of it!
The paragraph before what Roger quoted in XML 1st Ed
(http://www.w3.org/TR/1998/REC-xml-19980210) says:
A Name is a token beginning with a letter or one of a few punctuation
characters, and continuing with letters, digits, hyphens, underscores,
colons, or full stops, together known as name characters. Names
beginning with the string "xml", or any string which would match
(('X'|'x') ('M'|'m') ('L'|'l')), are reserved for standardization in
this
or future versions of this specification.
So assuming the above XML is legal, then all the xmlns:??? parts can ONLY be
namespace declarations.
Thus the 3 in xmlns:numberOfItems="3" can, in 'legal' terms, only be a URI,
and not an integer count that can be incremented / decremented etc. You
could of course argue that the 3 is actually a URI (and not a number) that
just so happens to represent the integer value 3!
