I've been trying to find a good source somewhere on how the workflow model xml-files are supposed to be structured (which tags where, and a thorough why and how), in order to implement what I want, but I feel the material is lacking. The community docs are either too fragmented, specific, or too general. Sure there are sources which say "If you wan't this, put this tag there", but there are seldom more explanation than that.
It might be I'm just ignorant, blind or stupid, but are there any detailed documentation somewhere which explain these xml files thoroughly? It feels I've been stumbling in the dark for weeks now :/
