Suggestion: drop isDeclared from Attributes/Attributes2 completely and 
instead define a new "undeclared" value to be returned by getType for 
undeclared attributes. I suspect this would have been in SAX/Java if 
anyone had thought of it earlier; but the use cases that led to these 
methods in Attributes2 weren't uncovered till later.

isSpecified is trickier, but I tend to think you should just add it to 
the Attributes interface and require parsers to support it.
