Is this paper freely available?
I would be interested in seeing a copy of it since I have recently been using with Drools
to detect all sorts of data conditions in XML documents.

There was my talk at IntelliFest 2012: "Reasoning with XML
Data".
Although it assumes that XML elements are unmarshalled into regular
Pojos, it may still contain some useful ideas and code snippets.
I'll send you the paper off-list, and I'd be interested to learn about
your reason for not converting to Pojos (using JAXB or similar).
