You're describing those things defined by PACKAGE_GROUP_* as package groups, 
which I would strongly advise against. I know the naming of PACKAGE_GROUP_* 
suggests that the two are part of the same thing but they really aren't. Most 
of this page apart from section 5 is actually talking about IMAGE_FEATURES and 
should be reworded as such if you want to reduce confusion rather than 
increasing it.

Paul
