To my reading, you're the one confused.  You explicitly said that "Namespace 
URIs clearly have three kinds of values..." and went on to list one of them as 
'Declared as no-value (empty string, "")', implying, to my mind, that SAX must 
deal with this case.  Tim rejoined that this case is erroneous, implying to my 
mind that it need not be dealt with in the SAX interface, but in 
error-handling.  I think Tim's clarification has eliminated a lot of the 
difficulty you were making about David Megginson's latest proposal.
