This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
"<H2 id="ceremony">Ceremony</H2>" This upper-case tag appears in the middle of a sample document (http://www.w3.org/html/wg/drafts/html/master/grouping-content.html#the-main-element) where all the other tags are lower-case. If it's intended to make the point that HTML5 can have mixed-case tags, then it should say so explicitly, but there are better ways to make this point; in its current context, it just looks inconsistent and a little confusing.
