It's not, but this is probably a bug BTW.  You can "undeclare" the
default namespace like so:

<root xmlns="foo" > 
 <child xmlns="" /> 
 </root> 

so why shouldn't you be able to undeclare other prefixes, e.g.

<root xmlns:foo="bar" > 
  <child xmlns:foo="" /> 
  </root> 

James Clark was the first to notice this, but that was after
namespaces had been out for a year.

BTW, *nobody* thinks it's a good idea to allow a namespace name 
to be an empty string - if the abovec were allowed, it would
strictly be in the interests of undeclaring prefixes; which
would break no existing namespace semantics.  Who knows,
it might even get done someday. -Tim
