clarity of example in Section 10.2

[Alex Yiu <alex.yiu@oracle.com>]

Hi, editor-team,

When I am applying changes for Issue 37 to Section 10.2.,  I am re-reading the example in that section.

If my reading is correct, we don't have invoice-CS related information in PurchaseOrderResponse, we may want to improve the clarity of the example by adding the following to the BPEL sample code.

----------------------
    <xsd:complexType name="PurchaseOrderResponse">
          <xsd:element name="CID" type="xsd:string"/>
          <xsd:element name="order" type="xsd:int"/>
              <xsd:element name="VID" type="xsd:string"/> <!-- *adding* -->
              <xsd:element name="invNum" type="xsd:int"/> <!-- *adding* -->
        ...
    </xsd:complexType>
----------------------

---------------
<bpws:propertyAlias propertyName="cor:vendorID"
    messageType="tns:InvMessage" part="IVC">
    <query>
    /IVC/VID
    </query>
</bpws:propertyAlias>
<bpws:propertyAlias propertyName="cor:invoiceNumber"
    messageType="tns:InvMessage" part="IVC">
    <query>
    /IVC/InvNum
    </query>
</bpws:propertyAlias>
<!-- *adding* -->
<bpws:propertyAlias propertyName="cor:vendorID"
    messageType="tns:PurchaseOrderResponse" part="IVC">
    <query>
    ...
    </query>
</bpws:propertyAlias>
<!-- *adding* -->
<bpws:propertyAlias propertyName="cor:invoiceNumber"
    messageType="tns:PurchaseOrderResponse" part="IVC">
    <query>
    ...
    </query>
</bpws:propertyAlias>
---------------

(BTW, we of course need to rectify the XPath used in the query subelement after passing Issue 103)

It should either look like this:
<bpws:propertyAlias propertyName="cor:vendorID"
    messageType="tns:InvMessage" part="IVC">
    <query>/VID</query>
</bpws:propertyAlias>

or look like this:
<bpws:propertyAlias propertyName="cor:vendorID"
    messageType="tns:InvMessage">
    <query>/IVC/VID</query>
</bpws:propertyAlias>


What do you guys think?
