Multiple result set from a Stored Proc using LINQ

hi,
I have a admittedly weird stored proc which returns 0 or 1, but also returns an xml using select, which is the result i need.  now when i dragged the stored proc to the DBML the resulting method is returning int(which means it is returning only the return value not the select return result set.), if i change the method to return IMultiple Result , should it return all the result set? do i have to do anything else?

thanks
