Your problem is that you are confusing *scope* with *defaulting*.
The scope of a namespace declaration is the whole of the element
in which it is contained, including the element type.
So the comment below is true:

So it does, in the sense that the scope of the "edi:' prefix is the
element "x".  But the name "x" is not defaulted to the edi namespace;
it would have to be "edi:x" for that, or the edi namespace would
have to also be the default namespace through the presence of
an "xmlns='http://ecommerce.org/schema'" attribute.

Instead the namespace of "x" is the current default namespace if any,
or no namespace if there is no current default.
