[XML-SIG] saxlib

[Paul Prescod]

Nothing you propose will break JPython, for the simple reason that 
JPython is Python. But none of them will work with Java parsers "out of 
the box." And some of them are not even possible to implement for Java 
parsers (I guess you could call that "breaking JPython"):

You should propose this to David for all SAX implementations.

This would be possible to implement in a wrapper layer.

This is not implementable for Java parsers because Java packages are not 
first class. There would have to be a list of valid parsers "hanging around".

This is not too bad because classes are first class in Java. You would 
just ask the class for its name (as you would in Python).

Java parsers won't have version numbers. You should ask for this to be 
added to the SAX API.
