I cannot agree more.

Scott, please be patient, some corporations are using "we might donate
this to Apache" arguments to gain PR resonance and given that Sun lacks
far behind in XML (but they want to catch up quickly, for example, by
hiring people like Norman Walsh and Eve Maler) their managers are trying
to gain every possible extra-momentum they can get.

But, please, don't let those things hurt you.

Just keep going the good job you've been doing so far, I'm sure people
will jump to help you now that you have a new codebase to work on.

(expect lots of bug reports from this list as soon as I place Xalan2
inside Cocoon2 and people start using it)

As for XSLTC developers.... we'll make sure the Spinnaker mistakes are
not done over again.

Stefano Mazzocchi      One must still have chaos in oneself to be
                          able to give birth to a dancing star.
