H_08 Heading level 7 correctly rolemapped to P

PDF125, PASS

Use case(s): Headings

Last updated on April 21, 2025

Description

The objective of this technique is to show how to tag headings with a heading level higher than 6.

Use a custom Hn tag that expresses the appropriate heading level. Role mapping an Hn heading tag higher than H6 to H6 allows assistive technology that does not support headings above H6 to nonetheless perceive a heading. Choosing an appropriate role mapping is at the discretion of the author. This example shows H7 rolemapped to P. H_09 shows H7 rolemapped to H6.

A simplified heading hierarchy, if appropriate to the content, is desirable. Role mapping an Hn heading tag higher than H6 to P can help to serve this purpose.

Note: For compatibility purposes and to avoid ambiguity, custom heading tags must use the letter H followed by Arabic numerals without any spaces or punctuation. For example, H1247 is permissible while "H1,247" and "H1 247" are not.
