Hi Patrick,
The rules for valid XML Literals include a requirement that the XML is
"exclusive
canonical XML" <http://www.w3.org/TR/xml-exc-c14n/>, not just valid and
well-formed XML (then comparing valid XML literals "is" comparing their
lexical forms).
Canonicalization includes requiring <x></x> form not <x/>.
