[Mono-devel-list] Assembly versioning

This is a side effect of the GAC.  You need your 1.2.3400 System.Xml
assembly installed into the GAC for mono to pick it up.

We should research why .NET loads assemblies that it has no support for,
I find that intriguing. 

.NET 1.0 has assemblies with versions 1.0.3300.0
.NET 1.1 has assemblies with versions 1.0.5000.0
.NET 2.0 (preview) uses 2.0.3600
