Import SAP ODATA XML into Mendix

Hi,

I am working on a client case where we would like to import data provided by a SAP Odata service back into a Mendix application.  As far as I can see i receive my response in a XML string which I need to import using an Import mapping.

In order to create an import mapping i require and XML Schema (XSD) - which is not provided by SAP's Odata service.  Do I manually need to create an XSD or are there more efficient ways?

Thanks,

Han Pieter
