I don't think this is necessary for the iterators, because you need all the
required user-provided operations for a given iterator category, and then
you get an iterator of that category -- in other words, you get all the
operations. The container docs differ because there are multiple sets of
container requirements, and the mapping is not nearly so simple.

That's a good idea. I'll do that.
