Roni:

Aha, I realize now that this draft isn't the product of an IETF working 
group, in which case, my points c) and d) below might not make sense.

But still I am confused with the namespace... I always thought that any 
XML document needs to indicate to which namespace their elements and 
attributes belong.

I found out that shipping implementations behaved according to the example and not the schema with a target name space. Pete suggested that the draft should align either to the example or the schema. So in order to capture the interoperability in shipping products it meant to have it as is now.
