Re: [XNI CHANGE PROPOSAL] XMLParseException changes and creation of XMLLocator2

The reason for creating a new interface was to not break anyone
implementing XMLLocator.
However, since it does not seem like we have too many implementations of
that interface around today,
It might be a better idea to stick this method in the same interface and
avoid the confusion of an XMLLocator2.

Why are you extending the interface instead of just adding the
method to the existing interface?

I know I'd have to update some of my XNI tools to add the method
but that XMLLocator2 just sticks out like a sore thumb. Especially
since it's the only interface that uses this naming convention. And
it's not the approach we've used in the past to update XNI interfaces
-- previously, we just changed the original interface.

This type of change is a lot more graceful than when we went from
start/endPrefixMapping to passing a namespace context object to the
startDocument method...
