[MapServer-users] classgroup and group for styles

[Jörg Thomsen (WhereGroup)]

Hello,

I've found an undocumented behavior of MapServer configuring different 
layer-styles. My questions are:

- Am I not able to find the documentation?
- Is it a wanted or an unwanted behavior?
- Am I wrong?

1st:
naming the classgroup and the group-item within the classes "default" 
the style does not appear in the capabilities. I think, if there are 
more than one style, both/all styles have to be provided in the 
capabilities.

2nd:
You need to name the classes, otherwise the style-names are not provided.
