Just to note... DCMI does not use (or recognise) the terms 'DC-full' and
'DC-brief'.  It tends to use the terms 'simple DC' (or sometimes
'DC-simple') and 'qualified DC'.  Definitions of these phrases are
provided in the document at


(which will hopefully move from a proposed recommendation to a
recommendation very shortly).

Assuming that you mean the same things by DC-brief and DC-full, I think it
would be very unhelpful to start using different terminology.
