Hi Marc,

It is true, that XPDL 1 is a subset of XPDL 2, but...

On the level of activities and transitions it is very similar, but in terms 
of details it is very different. We started Business Studio with XPDL1, and 
the hat to nearly completely rewrite it for XPDL2. The compatibility is on 
the schema level only; the interpretation is different... unfortunately. Not 
many things have changed, but new features changed the way how you model the 
processes in XPDL2. Mapping to XPDL1 will be completely different then 
mapping to XPDL2.

The XPDL2 introduce a lot of features that allows very seamless mapping 
to/from BPMN, without bending the rules and adding proprietary extensions as 
it was required in XPDL1. In many terms it will be easier to do mapping 
to/from XPDL2 as it is using more similar vocabulary to BPMN and even BPEL.

I can recommend focusing on subset of XPDL2, not on XPDL1, as we had to 
throw away a lot of the code for XPDL1 when we moved to XPDL2 in TIBCO.

Regards,
Wojciech
