Because we cannot replace
<foo:A xmlns:foo="[first URI]" xmlns:bar="[second URI]" >
<foo:B />
<foo:C />
<bar:D />
</foo:A>
with something like
<foo:A xmlns:foo="[first URI]" xmlns:bar="[second URI]" >
<:B />
<:C />
<bar:D />
</foo:A>
This is what I meant by inheritance of prefixes, and it does not exist
in the current working draft.
