First, it should be clear that this should hook in to the HTML spec's Rendering section, because this section has special rules when it comes to conformance classes and the use of words with requirements, as explained at the start of the section. http://www.whatwg.org/specs/web-apps/current-work/multipage/rendering.html#rendering This section also has this requirement: [[ The CSS rules given in these subsections are, except where otherwise specified, expected to be used as part of the user-agent level style sheet defaults for all documents that contain HTML elements. ]] I propose the following concrete text: [[ === Rendering === This section is to be treated as a subsection of HTML's Rendering section for the purpose of terminology, conformance classes and requirements. [HTML] CSS: ... the style sheet ... ]] Finally, I think the style sheet needs some tweaks. If we want <main> to have the same styles as <aside> (except for the effect <aside> has on <h1>, since <main> is not a sectioning element), I think the style sheet should be: @namespace url(http://www.w3.org/1999/xhtml); main { unicode-bidi: isolate; display: block; } Replace this rule in the HTML spec: :matches([dir=ltr i], [dir=rtl i], [dir=auto i]):not(address):not(blockquote ):not(center):not(div):not(figure):not(figcaption):not(footer):not(form ):not(header):not(hr):not(legend):not(listing):not(p):not(plaintext):not(pre ):not(summary):not(xmp):not(article):not(aside):not(h1):not(h2):not(h3):not(h4 ):not(h5):not(h6):not(hgroup):not(nav):not(section):not(table):not(caption ):not(colgroup):not(col):not(thead):not(tbody):not(tfoot):not(tr):not(td ):not(th):not(dir):not(dd):not(dl):not(dt):not(menu):not(ol):not(ul):not(li) { unicode-bidi: embed; } with: :matches([dir=ltr i], [dir=rtl i], [dir=auto i]):not(address):not(blockquote ):not(center):not(div):not(figure):not(figcaption):not(footer):not(form ):not(header):not(hr):not(legend):not(listing):not(p):not(plaintext):not(pre ):not(summary):not(xmp):not(article):not(aside):not(main):not(h1):not(h2):not(h3):not(h4 ):not(h5):not(h6):not(hgroup):not(nav):not(section):not(table):not(caption ):not(colgroup):not(col):not(thead):not(tbody):not(tfoot):not(tr):not(td ):not(th):not(dir):not(dd):not(dl):not(dt):not(menu):not(ol):not(ul):not(li) { unicode-bidi: embed; } 82085 1 faulkner.steve 2013-01-24 15:11:48 +0000 added to spec
