It looks like the extensibility package that was created to work with vCAC 5.2 is now part of the the vCAC 6.0 vCO plugin. As a general question where is the extensibility guide for 6.0 and/or the documentation for the vCO plugin? I think I have already posed this general plugin question in another thread but since I haven't received an answer I will be a squeeky wheel.
