[DL] Guideline to define new constructors in Description Logics

Well, there are quite a few defined description logics whose constructors
are not in the mainstream DLs.  This includes modals, time, space, and
fuzzy.  If you are interested in anything along these lines you should look
in the DL literature.

If you mean some specific construct for a particular domain (like, perhaps,
you want to define a family all at once), then you are probably looking at
a macro.   Macros have usability issues but don't impact the underlying

Otherwise you probably need to say more about just want you want.  Just
remember that any new expressive power needs new reasoning power, and could
easily impact the complexity or decidability of the DL.
