Description Simon Pieters 2009-04-02 14:36:28 UTC
Two issues:
1. <header>'s content model is wrong
2. outline algorithm is probably wrong

The spec says about <header>:

"Content model:
Flow content, including at least one descendant that is heading content, but no sectioning content descendants, no header element descendants, and no footer element descendants."

This means that


is allowed, since blockquote is sectioning root but not sectioning content.

Testing with and it appears that the outline algorithm doesn't ignore sectioning roots that are descendants of <header>.
Comment 1 Simon Pieters 2009-04-02 15:24:13 UTC
The outline algorithm says

"For the purposes of document summaries, outlines, and the like, the text of header elements is defined to be the text of the highest ranked h1–h6 element descendant of the header element, if there are any such elements, and the first such element if there are multiple elements with that rank. If there are no such elements, then the text of the header element is the empty string."

This should ignore sectioning root subtrees.
Comment 2 Geoffrey Sneddon 2009-04-02 15:40:42 UTC
No, that's under "the header element", not "creating an outline".
Comment 3 Ian 'Hixie' Hickson 2009-04-30 18:23:12 UTC
As far as I can tell this is now fixed, since <hgroup> can only contain h1-h6, and the new <header> isn't sectioning.
