I believe that all modern toilets have a 6 litre maximum capacity (hence the
rather pathetic looking -IMHO -diminutive cisterns). Is this correct?

I've recently fitted a modern toilet with a non-diminutive
cistern, although it is preset to the 6 litre mark. It could be
adjusted up to the (internal) overflow, but has worked OK.
