[xquery-talk] QName in content

[David Lee]

I suggest the "problem" is there are many "things" in XQuery which are not
serializable, or have decent well defined serialization.
QName is one, Attributes are another.    Document Order of nodes is another
interseting subtle example.
In XQuery 1.1 there are these new function objects you cant serialize
natively.

But that said, you *can serialize* anything by making up your own
serialization format.  E.g. you can query for the URI, prefix and localname
of QNames and serialize them in a synthetic element like
	<qname  uri="..." prefix="xxx" localname="xxx"/>

I don't see this as an inherent problem with XQuery itself, but rather a
mis-application of assumptions.

Florent,

The "uri" gets lost during the serialization. (loss of information,  
non roundtripable information, etc)

I am writing XQueries to process XSD schemas now (jnput and output).  
That's a big problem for me.
(I know I can use the XQuery 3.0's namespace constructors somehow, but  
the end result queries
are horribly complicated...)

Best regards
Dana
