[mapguide-users] Re: Add Mapguide layer to OpenLayers

[Michael Adair]

For untiled layers you can specify a mapName and session, or else a 
mapDefinition and locale.  See 
http://dev.openlayers.org/apidocs/files/OpenLayers/Layer/MapGuide-js.html#OpenLayers.Layer.MapGuide.OpenLayers.Layer.MapGuide 
for more guidance.
