Subject: [sca-bpel] NEW ISSUE: SCA-BPEL XML Schema

 

 

Resubmitting the new issue about the missing SCA-BPEL XML Schema -
please

add *this* one to JIRA.

 

I fixed the <element name="multiReference"> and added a
couple of comments

in the XML schema.

 

============================================================

 

 

TARGET:

SCA Client and Implementation Model Specification for WS-BPEL -
Committee

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 needed - see
(1)

- (4) in the proposal below.

 

 

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 ...

(See attached file: sca-bpel.xsd)

 

A. XML Schema

 

<?xml version="1.0" encoding="UTF-8"?>

<!--

      Copyright (c) OASIS Open 2008. All Rights Reserved.

-->

<schema xmlns="http://www.w3.org/2001/XMLSchema"

  
targetNamespace="http://docs.oasis-open.org/ns/opencsa/sca-bpel/200801"

  
xmlns:sca-bpel="http://docs.oasis-open.org/ns/opencsa/sca-bpel/200801"

  
xmlns:bpel="http://docs.oasis-open.org/wsbpel/2.0/process/executable"

   xmlns:sref="http://docs.oasis-open.org/wsbpel/2.0/serviceref"

   elementFormDefault="qualified">

 

   <!-- WS-BPEL 2.0 XML Schema for Executable Processes -->

   <import namespace="

http://docs.oasis-open.org/wsbpel/2.0/process/executable"

      schemaLocation="

http://docs.oasis-open.org/wsbpel/2.0/OS/process/executable/ws-bpel_executable.xsd

"/>

   <!-- WS-BPEL 2.0 XML Schema for Service References -->

   <import
namespace="http://docs.oasis-open.org/wsbpel/2.0/serviceref"

      schemaLocation="

http://docs.oasis-open.org/wsbpel/2.0/OS/serviceref/ws-bpel_serviceref.xsd

"/>

 

   <!-- WS-BPEL extension attribute for a variable representing an
SCA

property -->

   <attribute name="property"
type="bpel:tBoolean"/>

 

   <!-- WS-BPEL extension element for a variable representing an SCA

multi-valued reference -->

   <element name="multiReference">

      <complexType>

         <simpleContent>

            <extension base="string">

               <attribute name="partnerLinkType"
type="QName"/>

               <attribute name="partnerRole"
type="NCName"/>

               <attribute name="multiplicity"
type="sca-bpel:Multiplicity"

use="optional" default="1..n"/>

            </extension>

         </simpleContent>

      </complexType>

   </element>

 

   <simpleType name="Multiplicity">

      <restriction base="string">

         <enumeration value="0..n"/>

         <enumeration value="1..n"/>

      </restriction>

   </simpleType>

 

   <!-- WS-BPEL extension attribute for a partner link associated
with an

SCA multi-valued reference -->

   <attribute name="multiRefFrom"
type="bpel:BPELVariableName"/>

 

   <!-- XML Schema element representing an SCA multi-valued
reference -->

   <element name="serviceReferenceList">

      <complexType>

         <sequence>

           <element ref="sref:service-ref"
minOccurs="0" maxOccurs="

unbounded"/>

         </sequence>

      </complexType>

   </element>

 

</schema>

 

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>

Shouldn't the  <element name="multiRefFrom"> in the
