Actually, no it doesn't. If everyone upgraded to Java 2
then by adopting my proposed mechanism we'd have a
flawless backwards and forwards compatible migration
Given that the Java 2 requirement isn't acceptable, then
option (2) depends on us being willing to put up with
a (hopefully short) migration period during which there
will be interoperability problems with combinations of
SAX2 clients and SAX1 parsers.
I think that's a price worth paying, given that SAX is
still quite a young API ... we should get it right
_now_ while there's still time. And getting it right
means making sure that the API is as simple and
comprehensible as possible, which is what option (2)
offers. The getProperty() mechanism should ensure that
this problem is much less likely to come up again soon.
I'm pretty sure that this is what Tim meant.
