I notice this in 11.2.1.2:

used in conjunction with optional, it can be used to test whether a 
graph pattern with at least one variable in it has been matched. When 
also used in conjunction with not, it can test to see that a triple 
has not been asserted. This is called Negation as Failure in logic 
programming.

but NOT does not appear in the grammar anywhere. Is this an editing 
bug, or am I missing something?
