[bpel4people] New Issue: Actual Owner Missing in WS-HumanTask Context

[Dieter Koenig1 <dieterkoenig@de.ibm.com>]

Target: WS-HumanTask 1.1 specification,
section 7.4 Providing Human Task Context, ws-humantask-context.xsd

Description: BPEL4People provides the getActualOwner
XPath extension function. Other WS-HumanTask Parent applications may be
interested in the actual owner of a task as well. However, the actual owner
of a task is currently not communicated back to the calling WS-HumanTask
Parent.

Proposal: Add a child element "actualOwner" of type "htt:tUser"
to the WS-HumanTask context data type "tHumanTaskContext". 

   <xsd:complexType
name="tHumanTaskContext">
      <xsd:sequence>
         <xsd:element
name="priority"
type="htt:tPriority"
minOccurs="0"/>
         <xsd:element
name="peopleAssignments"
type="tPeopleAssignments"
minOccurs="0"/>
         <xsd:element
name="isSkipable"
type="xsd:boolean"
minOccurs="0"/>
         <xsd:element
name="expirationTime"
type="xsd:dateTime"
minOccurs="0"/>
         <xsd:element
name="outcome"
type="xsd:string"
minOccurs="0"/>
         <xsd:element
name="attachments"
type="tAttachments"
minOccurs="0"/>
         <xsd:element
name="actualOwner"
type="htt:tUser"
minOccurs="0"/>
      </xsd:sequence>
   </xsd:complexType>

Alternative Proposal: Split the
WS-HumanTask context into an inbound and an outbound context, and add the
actual owner to thr outbound context.

   <xsd:complexType
name="tHumanTaskRequestContext">
      <xsd:sequence>
         <xsd:element
name="priority"
type="htt:tPriority"
minOccurs="0"/>
         <xsd:element
name="peopleAssignments"
type="tPeopleAssignments"
minOccurs="0"/>
         <xsd:element
name="isSkipable"
type="xsd:boolean"
minOccurs="0"/>
         <xsd:element
name="expirationTime"
type="xsd:dateTime"
minOccurs="0"/>
         <xsd:element
name="attachments"
type="tAttachments"
minOccurs="0"/>
      </xsd:sequence>
   </xsd:complexType>

   <xsd:complexType
name="tHumanTaskResponseContext">
      <xsd:sequence>
         <xsd:element
name="outcome"
type="xsd:string"
minOccurs="0"/>
         <xsd:element
name="attachments"
type="tAttachments"
minOccurs="0"/>
         <xsd:element
name="actualOwner"
type="htt:tUser"
minOccurs="0"/>
      </xsd:sequence>
   </xsd:complexType>
