With regards to the CGI. It turns everything off that is not "STATUS DEFAULT" off so all layers start from the same state (e.g. off) and must be explicitly requested to be drawn or query. That common state made (at least in my mind) implementations easier. I mean, if a layer "lakes" started ON the doing layer=lakes would turn it OFF. So I wanted to remove the ambiguity of a starting state.
So, from the CGI point of view if it's not a default layer then consider it off and you must request it. Does that help?

But in practice, I'm not seeing the difference between ON and OFF. http://mapserver.gis.umn.edu/docs/faq/default_vs_on_vs_off has a promising description, but doesn't seem accurate either. When I query layers=all, I get layers with both ON and OFF status,. When I omit layer/layers from my query entirely, I don't get any ON images, just DEFAULT ones. What CGI query will return the layers with ON or DEFAULT set, but no OFF layers? thanks, -natevw
