The best place to raise Saxon queries like this is on the forums or bug
trackers at http://saxonica.plan.io. The xquery-talk list is for questions
about the XQuery language, not product-specific implementation issues.
We are investigating whether current releases of Saxon should still work on
.NET version 2.0, and will get back to you off-list. The answer may well be
that you need to upgrade to .NET 3.5.
