Yeah. What I understand is that the ability to locally bind namespaces is
critical to the ability to stream process XML document composition, an
element can define its own namespace prefix binding context. We recently
went over this when I declared a namespace best practice of declaring the
namespace bindings at the root element. I still maintain this is a best
practice but best practices are meant to be broken for such efficiency
reasons, and hence the ability to declare local namespace bindings is the
correct one (IMHO)
