I'm just formulating theme for my PhD thesis. Finally I decided that
"Implementing XSLT 2.0 in .NET" will be an interesting one. As am I
thinking about this topic, there are several ways to go:

1. Automatically translate Java code of Saxon to C# (this is the way you

2. On-the-fly translation of XSLT 2.0 stylesheet into XSLT 1.0 + EXSLT +

3. Write own XSLT 2.0 engine on the top of XQuery/XPath engine in .NET
Framework 2.0

4. Write whole XSLT 2.0 engine from scratch
    - as interpreter
    - as preprocesor which generates C# code
    - as direct MSIL code (.NET byte-code) generator

I plan to explore all possibilities and of course we can share
experience from 1st approach.

It is hard to predict something before detailed analysis, but I think
that finally I will use 2nd or 3rd approach as it allows reuse of very
fast XLST (or at least XPath) engine in .NET and allows smooth
integration with rest of System.Xml -- using XmlDocument or
XPathDocument as source tree representation, modelling XSLT API after
