Comment (by ruslik):

 Replying to [comment:7 darthaud]:

 I think there also should be a way to generate unique IDs for sub-level
 ULs to make output valid HTML (with current patch I don't see a way to do
 it). Maybe introduce static class property with index or something like
 that and then add it to filter args.
