A key is defined with the xs:key element and its child elements 
xs:selector and xs:field, see 
http://www.w3.org/TR/xmlschema-0/#specifyingKeysAndtheirRefs

Whether that tool you mention is then able to generate keys I don't 
know. You might want to check its documentation or find out whether 
there is a support forum or mailing list.
