Narrative:
During taxi out, on recall during the taxi checklist, the overhead light illuminated. The fdr 'off' light was illuminated. The MEL book was referenced and maintenance and operations notified. The MEL states the aircraft cannot be 'dispatched' from a maintenance base (ZZZ and XXX). We conferred with maintenance and dispatch and determined since we had blocked out from the gate that we were 'en route.' therefore, an 'en route MEL' was appropriate. Upon arrival at YYY, dispatch notified us that the interpretation of en route might be changed and the interpretation of en route might be changed and the company was trying to determine whether or not we were actually en route or not.
