I forgot to mention:
I believe the common case for attributes is a very small number of
attributes. Having one element with many attributes is quite uncommon.
This is one consideration when making improvements and optimizations
here. Making sure the pathological case is not terribly slow is good,
but we also want the normal case to be super-fast.
