BPMN21 — Beta 1 Spec: New Annex?: Enumerate the validation rules of BPMN

This is number 3 of 12 issues submitted by Bruce Silver

Enumerate the validation rules of BPMN. Back in the old days when the BPDM guys kept saying BPMN 1.0 had no explicit rules or metamodel, you said it did but it was buried in the narrative. Now you have an explicit metamodel but the rules are still buried in the narrative, and inconsistent from one part to the next. Judging from v1.x it will take years to clean up the narrative, so just enumerate the rules in one place and say this overrides contrary info elsewhere in the narrative.
