   When serializing AERecords as SOAP structures, it is possible
   to specify the namespace and type of the structure.  To do this,
   add a keySOAPStructureMetaData record to the top level of the
   record to be serialized.  If present, this will be used to specify
   the structure namespace.  This will produce a structure elment that
   looks like:

    <myStruct
        xmlns:myNamespace="http://myUri.org/xsd",
        xsi:type="myNamespace:MyStructType">

   Fills a buffer with a flattened representation of the
