A data format is not a 'container' for maps, it's a container for data.
The container for your maps should be something like WMC (though I
don't know if it makes sense off the web): grouping together datasources
and SLD and the like. The first half of the things you identified:

are things which are provided by SLD and the like, which means that you
really want SDF + WMC -- I don't think that this is SDF's job, and I
don't think that it should be the job of any geodata format.
