Just to clarify, the way I now understand this is that you cannot specify a
default namespace in an instance document unless the root element is from a
separate qualified namespace.  Is this correct?

Exactly what it says -- you have (by default) specified that
locally-declared elements (which 'publisher' is) must appear
unqualified, but by using a default NS decl in your instance, you've
caused it to appear qualified.

Either use an explicit prefix on the document element only in your
instance, or add "elementFormDefault='qualified'" to your xs:schema
elements.

This is a FAQ, sorry for the brief answer, there must be a longer one
around somewhere . . .
