AW: [MAPSERVER-USERS] Hiding overviews

[Pål Kristensen]

Hi! Daniel!

Yes, this is indeed what I'm trying to achieve. I can't answer for others,
but for what I've read it looks like the described behavior is what most
people wants. I guess someone would like the ability to totally hide some
layers from the capabilities document, but in my opinion that's more of a
cosmetic need not to disclose to the user how the layers are organized
internally in mapserver. After all a layer without a name is not queryable,
and that is the main objective. 

Regards,
Pål Kristensen
