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.
