I think too we shoud choose something all together and try to use
osgeo-standards mailing list to make lobby and help OGC to go in a good
direction.
As we are dealing with OGC standards, why don't we use the solution
already used by WMS?
well, it's a bit I'm not revisioning the specs but should be something
like this:
<layer>
<title>my group of level 1</title>
<layer>
<title> my group of layer 2</title>
<layer>
<name>layer_1</name>
....
</layer>
<layer>
<name>layer_2</name>
....
</layer>
</layer>
<layer>
<name>layer3</name>
</layer>
</layer>
ciao
