The following sections only cover conforming elements and features.
This section is non-normative.
An asterisk (*) in a cell indicates that the actual rules are more complicated than indicated in the table above.
† Categories in the "Parents" column refer to parents that list
the given categories in their content model, not to elements that themselves are in those
categories. For example, the a element's "Parents" column says "phrasing", so any
element whose content model contains the "phrasing" category could be a parent of an
a element. Since the "flow" category includes all the "phrasing" elements, that means
the th element could be a parent to an a element.
This section is non-normative.
* The tabindex attribute can also
make any element into interactive content.
