<plnk:partnerLinkType name="VendorPartnerLinkType"
  xmlns:plnk=
    "http://schemas.xmlsoap.org/ws/2003/05/partner-link/">
  <plnk:role name="serviceProvider">
    <plnk:portType name="po:POService"/>
  </plnk:role>
  <plnk:role name="client">
    <plnk:portType name="po:POServiceCallbacks"/>
  </plnk:role>
</plnk:partnerLinkType>

Example 14.15 - A partnerLinkType construct that references two portType constructs. (This code resides in the WS-BPEL process definition, not in the WSDL definition.)


<plnk:partnerLinkType name="VendorPartnerLinkType"
  xmlns:plnk=
    "http://schemas.xmlsoap.org/ws/2003/05/partner-link/">
  <plnk:role name="serviceProvider">
    <plnk:portType name="po:POService"/>
  </plnk:role>
</plnk:partnerLinkType>

Example 14.16 - A partnerLinkType construct that references a single portType construct.


<bpws:property
  xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
  name="PONumber" type="xsd:integer"/>

Example 14.17 - A property declaration of type xsd:integer.


<bpws:propertyAlias
  xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
  messageType="po:msgSubmitOrderRequest"
  part="PurchaseOrder"
  propertyName="po:PONumber"
  query="/po:purchaseOrder/po:poNumber"/>

Example 14.18 - A bpws:propertyAlias element being used to find the value for the PONumber property in the msgSubmitOrderRequest message.

Example 14.19 - An abbreviated WSDL definition that highlights the extensibility elements introduced by the WS-BPEL language.
