A valid XML 1.0 document has to declare all attributes used, even
magic attributes like xml:space, xml:lang, and xmlns and xmlns:*.
Nothing in the namespaces REC changes the interpretation of XML 1.0.

All names beginning with the letters [xX][mM][lL] are reserved, and no
other names are: only specs from the W3C's XML Activity should define
names beginning with these letters, and even then, we're trying to
avoid them.
All the best,
