I had an action item to combine the existing H69 with the description text I had previously proposed for H42. Here is the proposal which would be the new description of H69... some 
The objective of this technique is to use section headings to convey the structure of the content, and to create chunks of information that can be found easily by people with disabilities, such as a blind person using a screen reader, or a person with a cognitive disability who uses assistive technology that delineates groups of information, or someone with a communication disability or illiteracy, who uses a screen reader to assist them in their reading. Since headings indicate the start of important sections of content, it is possible for users with assistive technology to jump directly to the appropriate heading and begin reading the content. This significantly speeds interaction for users who would otherwise access the content slowly. Heading markup can be used to:

indicate start of main content
mark up section headings within the main content area
demarcate different navigational sections like top or main navigation, left or secondary navigation and footer navigation
markup images (containing text) which have the appearance of headings visually.
In (X)HTML, headings are designed to convey logical hierarchy. Skipping levels in the sequence of headings may create the impression that the structure of the document has not been properly thought through or that specific headings have been chosen for their visual rendering rather than their meaning. Authors are encouraged to nest headings hierarchically where the most important information is given the highest logical level, and subsections are given subsequent logical levels.(i.e., h2 is a subsection of h1). 
If the generic visual presentation of a particular heading level is not what is desired by the author (e.g., font size), Cascading Style Sheets (CSS) can be used to change the way headings look or sound. It is even possible to style headings using CSS so that they are exposed to assistive technology but are hidden from view visually. However, showing the headings visually benefits a wider set of users, including those with some cognitive disabilities. Be sure not to use CSS to mark up the <p> tag to look like a heading, because although it would visually look like a heading, assitive technology would not recognize it as such. Also, do not use heading markup to style text that is not a heading, because this would
