It is a fairly esoteric topic and the annotations are rarely needed
(the low-level kernel code is quite special in this regard), so don't
get too upset with the authors! (I don't talk about them in my book
either---there simply was no obvious need/opportunity to introduce
them).
The directives are explained in the Itanium assembler manual from Intel.

Chapter 7 is the one of interest here.
