Oops.  I just realized you can't do this.  Namespace attributes apply to the element where they 
occur and all children.  Thus, the following declaration places the Doc element 
in the IBTWSH namespace, which is a validity violation of the XSchema DTD.

<Doc xmlns="IBTWSH URI">

There doesn't seem to be a way that we can say we want all elements beneath (but 
not including) the Doc element to be in the IBTWSH namespace.  Instead, the 
instance will need to either use a prefix (which we can declare in Doc) or 
change the default in all elements directly beneath Doc.  Same applies to More.
