You mean "I don't see why the inner... *cannot be* or *is not* removed"

It can.  Having it there, or not, does not change the semantics of the 
XML.  It's just a side-effect of whatever implementation you are using.

If you really care about this -- for example, doing XML Digital Signatures 
-- then you need something like xml c14n.  Otherwise I would not worry 
about it.

dont see why the inner scope namespace declaration element be removed and 
use the parent namespace.

!  That's good to know...

I guess it all comes down the fact that the prefix isn't expanded to
the URI.... which is the root cause of the problem of XPath requiring
the prefixes to be mapped elsewhere.

I guess there is an argument for dropping the URI altogether, and just
using the prefix.  Some things would get harder, but many more would
get a lot easier.
