BPMN — Mapping to BPEL should be moved to the appendix

Since BPMN is considered to provide a business-level representation of processes (i.e., a PIM), it is appropriate that the mapping to BPEL be moved to the appendix. In addition, the BPEL mapping should not be defined as a normative part of the specification since BPEL is viewed as a platform/execution language. In other words, the transformation could be different depending on the particular implementation of BPEL. A normative mapping to WSDL and choreography (which might be expressed in BPEL) is needed, but should be a mapping from a normative BPMN metamodel rather than the graphical notation.
