Consume External OData in SAP Gateway

I have metadata service that looks like this...

<edmx:Edmxxmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx"Version="1.0">

</edmx:Edmx>

This does not make it pass the parsing. I debugged and found in class /IWFND/CL_OCI_PARSER they are replacing certain schemas in the compose_unrecognized method.

  DATA: ls_unrec TYPE ty_s_unrec   .

*  ls_unrec-actual   = 'MaxLength="Max"'.
*  ls_unrec-expected = 'MaxLength=""'.
*  APPEND ls_unrec TO mt_unrecognized .
*
*  ls_unrec-actual   = 'MaxLength="MAX"'.
*  ls_unrec-expected = 'MaxLength=""'.
*  APPEND ls_unrec TO mt_unrecognized .

   ls_unrec-actual   = 'xmlns="http://schemas.microsoft.com/ado/2007/05/edm">'.
   ls_unrec-expected = 'xmlns="http://schemas.microsoft.com/ado/2008/09/edm">'.
   APPEND ls_unrec TO mt_unrecognized .

* Example: http://www.nerddinner.com/SERVICES/ODATA.SVC/$metadata
   ls_unrec-actual   = 'xmlns="http://schemas.microsoft.com/ado/2006/04/edm">'.
   ls_unrec-expected = 'xmlns="http://schemas.microsoft.com/ado/2008/09/edm">'.
   APPEND ls_unrec TO mt_unrecognized .

* Example: Azure market place services
   ls_unrec-actual   = 'http://schemas.microsoft.com/ado/2009/08/edm'.
   ls_unrec-expected = 'http://schemas.microsoft.com/ado/2008/09/edm'.
   APPEND ls_unrec TO mt_unrecognized .

Does anyone know if this could be updated, perhaps even made into a customizing table?

Thanks,

Alex
