At this point, I’d like to point out that absolutely no one reads the spec from top to bottom. Rather, only look at the section corresponding to what you are trying to look for, and in that section only look at what you need. Try to determine which one of the five big sections your specific question relates to; and if you are having trouble determining which one it is, ask yourself the question "at which time is this (whatever you are trying to confirm) evaluated?" which may help. Don’t worry, navigating the spec will only become easier with practice.
