10. Rendering

This section will probably include details on how to render DATAGRID (including its pseudo-elements), drag-and-drop, etc, in a visual medium, in concert with CSS. Terms that need to be defined include: sizing of embedded content

CSS UAs in visual media must, when scrolling a page to a fragment identifier, align the top of the viewport with the target element's top border edge.

10.0.1. Section headers

For h1 elements, CSS-aware visual user agents should derive the size of the header from the level of section nesting. This effect should be achieved by including the following rules, or their equivalent, in the UA's user agent style sheet:

@namespace xh url(http://www.w3.org/1999/xhtml);
xh|section xh|h1 { /* same styles as h2 */ }
xh|section xh|section xh|h1 { /* same styles as h4 */ }
xh|section xh|section xh|section xh|h1 { /* same styles as h4 */ }
xh|section xh|section xh|section xh|section xh|h1 { /* same styles as h5 */ }
xh|section xh|section xh|section xh|section xh|section xh|h1 { /* same styles as h6 */ }

Authors should use h1 elements to denote headers in sections. Authors may instead use h2 ... h6 elements, for backwards compatibility with user agents that do not support section elements.

must define letting the user obtain a physical form of a document (printing) and what this means for the UA

Must define that in CSS, tag names in HTML documents, and class names in quirks mode documents, are case-insensitive.
