If you have control of the files, and the only user inputs are  
predicates for "where"
clauses, and documents, there is not much to worry about.

If you are using BDB XML's schema validation, you should know that
if the parser cannot find the referenced DTD, it backs out to well- 
formed
parsing, so potentially a user could supply a bad doc with a bad DTD
reference, but it still needs to be well-formed XML.
