Thanks for your reply Jukka. The reason for the single layer in the WMS request is that the other layer has a "STATUS default" which I understood to mean that it was always returned regardless of the value in the WMS layers parameter. Indeed this has been my experience, problem is that the default layer is always at the bottom of the draw order.
