What If BPMN Were a Modeling Language?

Lacking support for fundamental concepts like human tasks and subprocesses, BPEL has become a favorite whipping boy of BPM vendors and consultants.  But for all its faults, BPEL enjoys something that BPMN advocates can only dream about: an XML storage and interchange format that makes sense.  It’s often said that BPEL is an XML language not a graphical notation, but the reality is that graphical BPEL design tools all use more or less the same notation, based on a simple mapping to native BPEL language constructs: Receive, Reply, Invoke, etc.  BPMN has a standard notation, but still lacks a standard storage and interchange format consistent with the fundamental goals of BPMN itself.
