Top down approach(WSDL to copybook) for IMS SOAP

Our customer has decided to adopt interface centric design using WSDL. We have several environments including Web Services requester and provider. So we must have both top-down approach (WSDL to COBOL copybook) and bottom-up approach (COBOL copybook to WSDL). But now there is nothing pure top-down approach tool which generates copybook from WSDL without any middleware attributes in RD/z. We strongly require this function tool in RD/z. Now only CICS Web Services on EST in RD/z provides top-down approach. But our customer environment is IMS. So IMS SOAP Gateway must have the function both of top-down and bottom-up approach in RD/z product.
Especially, when IMS becomes the SOAP requester(IMS called callout request), IMS user has to prepare additional WSDL-related copybook. If RD/z EST for IMS will provided the Top-down approach wizard like RD/z EST for CICS for generating copybook, IMS user does not need this extra work that he has to map between WSDL and copybook. If RD/z provide this function and provide copybook generated from WSDL in its proper situation, IMS user's work is greatly reduced like CICS user.

When the function of this requirement is offered, it is necessary to offer the following functions at the same time.
1. In the field elements of copybook generated from the XSD elements in WSDL, it makes the copybook field elements that was corresponding to the XSD structure without adding an unnecessary attribute just before the element. Because RD/z EST for CICS adds this extra attribute in front of the field element, we can not use the RD/z EST for CICS's Top-down approach.
2.The COBOL's storey level of the first field of the copybook generated by RD/z EST for IMS and the interval of the next storey level can be specified using the option attributes.
