I think there is a problem with the xs:pattern used for the http://schemas.microsoft.com/2003/10/Serialization/:guid type. In XML Schema, the "\d" multi-character excape translates to "\p{Nd}", which matches any character with a Unicode General Category of "Nd". This is much more permissive than System.Guid. The problem with this is that the following are all valid guids according to the pattern, but none of them can be deserialized as System.Guid:

Hi Kevin-

That's something I noticed as well. I know why the code does what it does but I need to do some archeology to find out why that schema was picked.
