From http://www.w3.org/XML/xml-names-19990114-errata "The prefix xmlns is used only to declare namespace bindings and is by definition bound to the namespace name http://www.w3.org/2000/xmlns/. It must not be declared. No other prefix may be bound to this namespace name" -- PITHY WORDS OF WISDOM We all work under a slight handicap, we're human.
