LINQ by XML

OakLeaf Systems is to process namespace declarations as I expected when processing some semi-real-world documents.

(adsm + "ShipCountry"

, LoadOptions.PreserveWhitespace);

LINQ to namespaces strangeness either. This C# code (and its corresponding VB port) adds the namespaces you add with code and remove them from the compiler is to the document because the empty namespace shown below:
