Section 3 contains the following language which was copied from the 1.0 spec 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. This is not sufficient for Namespaces 1.1. In particular it does not forbid the undeclaration of the xml prefix. The following appears to be legal following a strict reading of this draft: xmlns:xml="" This is because section 6.1 states, "The attribute value in a namespace declaration for a prefix /MAY/ be empty. This has the effect, within the scope of the declaration, of removing any association of the prefix with a namespace name. " In other words the empty string is not a namespace name and therefore it is not illegal to say xmlns:xml="". I assume this is an oversight, not a deliberate design decision. In this case, it can easily be fixed by adding a sentence to section 3 along these lines: The xml prefix MUST NOT be undeclared. -- Elliotte Rusty Harold
