how do you include MDM WSDL when setting up an XI interface

I am trying to use XI to pull data from MDM. In XI when I try to create my interface object and enter a WSDL file for MDM I have a problem because SAP MDM generates 3 separate WSDL files; if you go to http://sapjl0ci.intel.com:50100/wsnavigator/jsps/explorer.jsp?localWS=TURNU2VhcmNoUmVjb3Jkcy9zYXAuY29tJTJGdGMlN0VmYWNhZGUvc2FwLmNvbSU3RXRjJTdFZmFj%0D%0AYWRlLndzYXI%3D you can see the different MDM WSDL downloads. When you download one of the options, it creates the WSDL into 3 separate files. But in XI there is only the option to enter one WSDL file. Any idea how to get around this ??
