[boost] Type Traits Documentation Outdated?

It seems like the type traits docs have suffered some stagnation over time. For example, is it documented somewhere that almost all the traits are also Metafunctions? Also, the "guidelines for integral constant expressions" probably ought to be updated to recommend the use of MPL operations on integral constant wrappers instead of the baroque and long-winded ice_whatever templates.
