what I wanted to say in my last comment (sorry for that, sent it too
early), was that in JWT we are aiming for genericity. That means that we
will certainly have a look at BPEL later on, but currently we are first
focusing on XPDL. At the moment the STP BPEL project lays stress on that
topic, so we don't interfere on them.
However, we already made a small proof of concept that BPEL code can be
generated from the modeller, but this was still in an early stage and will
not be maintained in the next months.
