[boost] Deciding what to put in `namespace detail`

For my future Boost.RDB submission, I feel tempted to put everything 
except the names that are in the public (documented) interface in a 
nested `namespace detail`. Why not even put *everything* there and copy 
selected names in the public namespace by means of using-declarations. 
Has it been already done ? And what about having three namespaces : a 
"public" one for the user, a "protected" one for those extending the 
lib, and a "private" one for undocumented internals?

Opinions and advise welcome...
