Re: FLD "required" vs "expected" to be used for all RIF logic dialects

The whole purpose is to impose a standard on how logic extensions are going to
be defined. Otherwise, we will have open season for introducing all kinds of
kludges. Note that the document says that, if necessary, FLD will be extended
to accommodate other logic-based dialects. But this should be done with extra
care and not on a whim.
