[Exist-open] added XML fragment not being indexed when inserted using update extension?

[William B. <wh...@ca...>]

Hi,

I have a very odd problem with XQuery not returning some of the data 
from inside an xml fragment that was inserted using the XQuery update 
extension (Using exist 2005/08/05 snapshot):

My document looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF xmlns:ib="http://www.cl.cam.ac.uk/~whb21/intelligentBook#" 
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"

    <rdf:Description rdf:about="http://abc.net.au/news/default.htm">
        <rdf:type

        <ib:topic xml:lang="en">news</ib:topic>

        <dc:Description xmlns:dc="http://purl.org/dc/elements/1.0/">News 
from the ABC</dc:Description>

        <ib:type>Introduction</ib:type>
    </rdf:Description>
</rdf:RDF>


An XQuery of //rdf:Description run on the collection does pickup the top 
level fragment.  However, XQueries of:
 //rdf:Description/@rdf:about
//rdf:Description/ib:topic
or even //rdf:Description/@*
do not return the contents.

My suspicion is that this might be because the rdf:Description fragment 
was inserted using the XQuery update extensions -  essentially the 
important part of the XQuery that inserted it being
(update insert $c_fragment into $to)
where $c_fragment was the entire XML of the rdf:Description (including 
subelements) and $c_to was the top level rdf:RDF element.

Is only the top level element being indexed?  Or am I missing something?

Any solutions to this problem gratefully received!

cheers,
