wfmopen, an engine I looked at before/while choosing jBPM extentds xpdl by using namespaces. They do restrict themselves to functional information like variables, form info (they use xforms), "actionhandlers" Bendpoints will only be in transitions. They are often not that complex and the additional info will not disturb to much I think(well, hope) and color info should be kept to a real minimum (imo), mayby it should even be in a css file ;-) (just kidding). Personally I would not go for doing things two different ways (so no separate section for e.g. bendpoints. Maybe | <transition name="to_state" to="first"> | <gpd:edge> | <gpd:bendpoint x="23" y="45"/> | <gpd:bendpoint x="34" y="23"/> | <gpd:bendpoint x="45" y="43"/> | <gpd:bendpoint x="56" y="26"/> | <gpd:bendpoint x="23" y="12"/> | </gpd:edge> | </transition> | could be rewritten as | <transition name="to_state" to="first" gpd:poly="23,34,11,-22,11,20,11,-17,-33,-14" | </transition> | But that could be totally incompatible with EMF,GEF or whatever eclipse framework is used.
