ACTION-101 Bare Arrays Issue

ACTION-101 Bare Arrays Issue

I took an action (http://www.w3.org/2005/06/tracker/databinding/actions/101) to investigate the issue raised by Microsoft (Item 7) in their last call comments. This was because of a request that BT had seen internally that we add 'wrapper' elements to repeated elements in schema's generated from our UML models to address 'implementation problem'. This sounded like the same issue at first but...

A bit of digging to find the driver for this request has shown that Siebels own 'Integration Objects' that are created  from the wsdl, and mapped to Siebel data types, can not have a cardinality of >1 assigned to basic datatypes, only 'components' (i.e. complex types.)

Example it cannot process a schema to create an instance doc as follows:

<m1:debtScheduleAction>

    <m1:type>Skip</m1:type>
    <m1:name>Partially Restricted</m1:name>
    <m1:name>Complete Restricted</m1:name>
    <m1:debtScheduleRestartDate>1967-08-13</m1:debtScheduleRestartDate>

</m1:debtScheduleAction>
but it can create:
<m1:debtScheduleAction>

    <m1:type>Skip</m1:type>
    <m1:name>
            <nameValue>Partially Restricted</nameValue>
    </m1:name>
    <m1:name>
            <nameValue>Complete Restricted</nameValue>
    </m1:name>
    <m1:debtScheduleRestartDate>1967-08-13</m1:debtScheduleRestartDate>

</m1:debtScheduleAction>


I don't know how we ought to view such a bizarre tool limitation wrt basic patterns. For discussion on the call?

Further to that we have seen requests for wrapped arrays from another source as well. In an integration layer that sits in front of BES/COTS we implement XSLT to convert between the SOA interafces and the bespoke XML of the BES. Their issue with bare arrays is that it is a far less efficient way of processing the document.
