The draft also says, "The namespace declaration is considered to apply
to the element where it is specified and to all elements within the
content of that element, unless overridden [...]."

That's "to the element", not just to its content.  The GI of an
element is part of it, so the example is conformant.

All names beginning "xml" or "XML" or "xML" or whatever are
already reserved.

That won't work.  What *is* the "isbn" namespace?  You haven't
specified its URI anywhere.
