I've just re-read it, and the clauses all seem to be satisfied in the
case in hand:
  2.1 is satisfied, because 'restriction' is not being passed in as a
  parameter, as it were;
  2.2 is satisfied, because 2.2.1 is satisfied.

What am I missing?

Note I am _not_ arguing that because these definitions are in the
sForS the primitive builtins are really derived, or that the
definitions in the sForS are sufficient -- these definitions are in
the sForS for completeness and documentation purposes, not because
they have real semantic bite: all the primitive builtins have
idiosyncratic semantics which is specified in the prose of the
relevant sub-section of the REC.
