I am using an ArcGISTiledMapServiceLayer. I know that I only want LODs 4 through 14. I don't want to hardcode the resolution/scale of these LODs. However, I have a catch-22 problem. I can only limit the LODs displayed on construction of the map; it doesn't appear that I can set them later. But I can't figure out the LODs available without loading the layer, which means adding it to a previously-constructed map. Does this mean I can only do this by constructing a map, adding the layer, determining the LODs, destroying the map, reconstructing it with the right LODs, and re-adding the layer? Surely it's not so inefficient.
