[sca-bpel] New Issue - Additional Integrity Constraints for SCA Extensionsto WS-BPEL

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."
