Sorry John, but I was actually thinking of a cross between the two,
where all xmlns attributes were inherited.
The advantages here are:
1. You can slip namespaces right past anything that isn't namespace aware;
2. You can manipulate the DOM without worries about scope;
3. You can strip the inherited values off on the output side, and have something
reasonably readable and predictable, with all the original xmlns attributes
preserved. (The names chosen may actually be meaningful to the author, mm?)
When you create new elements in such a DOM, the APPLICATION does need to
be aware of which namespace it is using, and supply the appropriate xmlns attribute.
That doesn't seem to be too much to ask.
