NEW ISSUE: How does a SCA Extended WS-BPEL Runtime deal with a non-conformantBPEL process?

Title: How does a SCA Extended WS-BPEL Runtime deal with a 
non-conformant BPEL process?

Target: SCA BPEL C&I

Description:
The spec says nothing about what a SCA Extended WS-BPEL Runtime must do 
when it encounters a non-conformant BPEL process containing SCA BPEL 
extensions. For example, if a PL contains both a sca-bpel:service and 
sca-bpel:reference attribute, the runtime can just ignore it and deploy 
the process/component. Other SCA specs have a requirement that the 
runtimes must raise an error when such problems are encountered.

Proposal:
Not a specific proposal, but a genera outline --
require the SCA Extended WS-BPEL runtime to generate errors (either at 
deployment or runtime) when the artifacts used (in our case the process 
definition) do not conform to our spec.
