No, they won't as Xquery's bias towards schema typing means that an
implementation is allowed to just use the typed value and junk the
original lexical string so if the original was
<Weight>123.456</Weight>
you might get away with it but if it's
<Weight>0<!--I added this leading 0 for a reason-->123.4560</Weight>
a query processor is allowed to report that as
<Weight>123.456</Weight>
and information is lost. It is lost because Xquery views the stated
typing as more important than the XML markup. It is essentially not an
XML processing language at all; it is language for querying typed trees.
