You're right, I was over-generalising a bit there.  The actual
requirement of Regulation 411.3.3 is to provide RCD protection for all
"socket-outlets with a rated current not exceeding 20A that are for use
by ordinary persons and are intended for general use".  This is
considerably broader than the requirement of the 16th edition; I don't
have the text to hand, but it was something along the lines of RCDs
being necessary for any socket that outdoor equipment might foreseeably
be plugged into.
