Thanks a bunch to Dieter for putting together the schema proposal.
Note that the CD drafts [1] we approved on the 1/17/08 conf-call [2] do
not include the schema either inline in the specification text or as a
separate file.
Do the TC members think it as important to conduct the CD approval vote
once again with a new set of drafts that include the schema? I
personally do. At the minimum, I would be hesitant to publish the CD
drafts without the schema to the OASIS doc repository.
On a side note - I think having the schema inline (in the
specifications) may be sufficient for the CD versions. For the later
stages (PR/CS/OS), we could publish the schema file separately.

> Draft 01.
>
>
> DESCRIPTION:
> The SCA-BPEL XML Schema (namespace
> "http://docs.oasis-open.org/ns/opencsa/sca-bpel/200801") is missing.
>
> Moreover, a number of minor XML Schema related changes are

>
>
> PROPOSAL:
> The XML Schema for the SCA-BPEL constructs needs to be made
> available as a
> standalone artifact (see attached file) and as an Appendix
> chapter in the
> spec - see below, something along the lines of the following ...

> In addition, the following changes should be made in the spec:
>
> (1) The SCA-BPEL namespace on line 195 is wrong, it should be:
> <extension namespace="
> http://docs.oasis-open.org/ns/opencsa/sca-bpel/200801"
> instead of
> <extension namespace="http://www.osoa.org/xmlns/sca/bpel/1.0"
>
> (2) The XML Schema syntax for the serviceReferenceList (lines 250-257)
> definition should have the orange background (used for
> syntax) instead of
> the grey background (used for examples).
>
> (3) The multiRefFrom attribute should reuse the type defined for BPEL
> variable names - in line 266, use
> <partnerLink ... sca-bpel:multiRefFrom="bpel:BPELVariableName" />
> instead of
> <partnerLink ... sca-bpel:multiRefFrom="xs:NCName" />
>
> (4) The BPEL service-ref element is defined in the namespace
> associated
> with the prefix "sref:", so the XPath expression in line 288 should be
> count($vendors/sref:service-ref)
> instead of
> count($vendors/bpel:service-ref)
>
> and in line 301
> <from>$vendors/sref:service-ref[$idx]</from>
> instead of
> <from>$vendors/bpel:service-ref[$idx]</from>
