I don't understand. The relevant spec text is: "The outline depth of a heading content element associated with a section section is the number of sections that are ancestors of section in the outline that section finds itself in when the outlines of its Document's elements are created, plus 1. The outline depth of a heading content element not associated with a section is 1." This seems pretty clear - the outline depths of the headings in the first snippet are, respectively, 1, 2, and 3, since that's how many sections (plus 1) are the ancestors of each. The same applies to the second snippet, since the implied sections generated by the headings produce the same virtual structure as the first snippet. What text are you looking at that implies the outline depths of the headings in the first snippet are all 1? ~TJ
