RelaxNG question

[Tim Bray <tbray@textuality.com>]

Suppose in a RelaxNG schema (compact syntax) I have

default namespace eg = "http://example.com/";
namespace noNS = ""

I'm writing a schema for something that will serve as a container, and I 
have an element for which I want to say "This can contain mixed content 
of more or less any elements/attributes with the constraint that no 
elements may be unqualified (noNS above), and no elements or attributes 
can be in my namespace ("eg" above).

I'm fiddling with name classes and "-" and having trouble getting it to 
do what I want.  There's an example in section 11 of the RNC tutorial 
that kind of does this with attributes. Anyone done this?
