  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."
