What query engine are you using?
From what I know, Saxon's free implementation doesn't support schema
aware XQuery.
On the other hand, BEA's products do support schema aware XQuery based
on XMLBeans schema type systems.

Subject: Import schema for schema aware XQuery
Hi
I have a situation where I need to use a schema-aware XQuery, so I can
ensure that what the query is asking for is possible in the schema.
I tried adding a line like this...
import schema default element namespace "" at "videos.xsd";
...to the beginning of my call, so I have something like this:
myXmlObject.execQuery("import schema default element namespace '' at
'videos.xsd';" + getQuery());
However, I get an error XPST0003 stating "Import schema must appear
earlier in the prolog".
So it appears that XmlBeans is adding some default statements to the
beginning of my XQuery.
Is there a way to get my import statement into the query in the right
place? Or is schema-aware XQuery not possible in XmlBeans?
Many Thanks
Paul
