Can the map's primary service that determines the spatial reference be defined by WKT?

The first service added to my map is an ArcGIS Server dynamic map service with a spatial reference defined by WKT rather than WKID.  When the map is displayed in the html viewer, the map area is white, but the coordinates look correct.  If I change primary service to one defined by WKID, so the original service is being projected on-the-fly, then both services are displayed perfectly.

  The answer is yes it can!

   

  My problem was the WKT for the problem service included a vertical coordinate system.  Once this altered to just the XY coordinate system the layer draws happily when it is the primary service.
