The binding must appear in the document. Any other behavior would make
it impossible for a user to know if inline content can contain
references to that namespace.

I believe that's an error. Suppose that instead of "<doc/>", my content
was "<doc>What about {c:foo}?</doc>"?

If you lose the c: binding,then the application that interprets the
meaning of content in curly braces doesn't have a binding to consult.

                                        Be seeing you,
                                          norm
