Re: Showstopper issue with new Attribute text

The infoset REC says that attributes named 'xmlns' have a namespace. 
For the [namespace attributes] property of element information items

namespace URI of http://www.w3.org/2000/xmlns/."


Oh crap. Does anything in the namespaces spec say this, or do we have 
another discontinuity between the specs? OK, I see it in the 1.1 spec:

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 or undeclared. Other prefixes MUST NOT be 
bound to this namespace name.

Yuck. This is simply horrible, but it is there.

Regardless, the prefix property of the namespace information item is 
*not* the same as the name property for the xmlns attribute. And an 
xmlns attribute information item is not the same as the namespace 
information item. The former comes from namespaces declared. The 
latter from namespaces in scope.

The local name property of the attribute information item for an 
xmlns attribute is xmlns. The prefix property for the attribute 
information corresponding to an xmlns attribute has no value. 
Therefore, when SAX reports these I maintain that the local name 
should be xmlns, not the empty string. The qualified name should also 
be xmlns. This is still a showstopper issue, even allowing xmlns 
attributes into the http://www.w3.org/2000/xmlns/ namespace.
