I'm with Mike, C# 3.0 needs the Visual Basic 9 XML Syntax.  Maybe "needs" is a strong word, since the functional construction model used for building XML with LINQ to XML is head and shoulders above what we have available in today's XML API's, but it sure would be nice!  Since the VB guys already have it done it should be a piece of cake to move over.  Those Microsoft guys have mad skills, I expect it to be in the next CTP! :)
