New description:

 {{{
 Please add the ability to partially specialize implementation_level using
 enable_if. The use I would appreciate is:

 template<typename T, typename Enable=void>
 struct implementation_level;

 template<typename T>
 strut implementation_level<T,enable_if<my_condition<T> >::type >
 {
    make_never_serialized_somehow;
 };

 If the above is not possible, please add an example to the documentation
 expressing how to achieve the above for a class of possibly unrelated
 types.

 Thanks
 }}}

 Can't reassign this to Robert Ramey until he sets up his email as
 described in TicketWorkflow.
