Wrong. The Namespaces Rec states:

Namespace constraint: Reserved Prefixes and Namespace Names

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.
