We are also doing some work on web services and XQuery, but more on the 
academic side ;-). I belong to a research group in databases, at INRIA, 

We mainly use XQuery to define SOAP web services, but let the queries accept 
parameters. We also let documents contain links to web services, which leads 
to an interesting recursive scheme, since the queries that define the 
services can apply on these documents.

We have a running prototype, using a simple variant of XQuery, that will be 
demonstrated in september at the VLDB conference.

For a detailed paper, please refer to:


For a description of the demo, see:

Comments are (very) welcome.
