Re: [xmljs-users] Namespace validation question

Hi Ilya,

Because XML namespace specification says so:

http://www.w3.org/TR/REC-xml-names/

"3 Declaring Namespaces

...

The prefix xml is by definition bound to the namespace name http://www.w3.org/XML/1998/namespace. It MAY, but need not, be declared, and MUST NOT be bound to any other namespace name. Other prefixes MUST NOT be bound to this namespace name, and it MUST NOT be declared as the default namespace."

Hope it answers your question,
Dmitry.
