Just like the one for AppCache.
http://dvcs.w3.org/hg/xhr/rev/8b3865161981 Though I might change my mind on this in the future. I'm not sure if marking things that are obviously non-normative is really worth it.
I particularly picked this section and didn't look at others because a of mime who thinks the event summary section of AppCache *isn't making sense* (well, a summary is just a summary) and I had to tell him that that section is only informational (non-normative) and he should look into the steps.
Consider this feedback as from a casual spec reader and feel free to do as you wish.
