Two part quesiton.

1.  Are namespaces only good for files?  If I declare using namespace x in a .h file, then I must also make that declaration in the .cpp file that includes that.  Is this correct?

2.  I am trying to do some xml stuff, and I declare using namespace MSXML2, but when I try to create a IXMLDOMDoucmentPtr I get an error because it is ambiguous.  why?

Ref 1: If you put using namespace into the .h, it is equivalent to putting it ito the .cpp, but it is bad practice because you are forcing anything that uses the .h to use the namespace.

Ref 2: See http://support.microsoft.com/default.aspx?scid=kb;en-us;316317
