Namespace cleanup

Based on the excellent feedback from jeremychapman, we've changed the namespace of this project to avoid collision with other schematron projects.

First release

This is the first release of the ported XRouter schematron project to support XPath2 and XSLT2 using XmlPrime. I've looked hard, and I couldn't find any other .NET or C# library to give me fast, native schematron validation of XML files.

It passes the original unit tests, and a few more have been added.
It's being used in a production environment against health information technology (HIT) schematrons, e.g. HL7 CDAs.

Of course, it would benefit from greater participation from the community in both usage and testing. So welcome to the team!
