TARGET: SCA Client and Implementation Model Specification for WS-BPEL, Chapter 3 "SCA Extensions to WS-BPEL"


DESCRIPTION: Chapters 3.2 and 3.3 of the SCA-BPEL spec introduce several SCA extensions to WS-BPEL partner links. The sca-bpel:multiRefFrom and sca-bpel:reference attributes are only meaningful for partner links used in outbound interactions. Conversely, the sca-bpel:service attribute is only meaningful for partner links used in inbound interactions.


PROPOSAL: Add normative constraints to chapter 3 in order to avoid contradicting (and therefore useless) partner link attribute specifications.

Add the following to section 3.2:
"The sca-bpel:multiRefFrom attribute MUST not be specified for a partner link with a myRole attribute referencing a role which is the only role of a partner link type. Furthermore, sca-bpel:multiRefFrom attribute MUST not be specified for a partner link that has the sca-bpel:service attribute."

Add the following to section 3.3:
"The sca-bpel:service attribute MUST not be specified for a partner link with a partnerRole attribute referencing a role which is the only role of a partner link type." and "The sca-bpel:reference attribute MUST not be specified for a partner link with a myRole attribute referencing a role which is the only role of a partner link type."
