Response from the Working Group
Thank you for identifying the further clarity needed regarding the
differences in techniques H42 and H69.

Technique H42 is a sufficient technique for SC 1.3.1 but not SC 2.4.1
because H42 only addresses marking up headings that already exist in
the page.

SC 2.4.1 requires adding headings where they may not have been part of
the original page in order to use heading markup as a mechanism to
bypass blocks of content. This potentially makes technique H42
insufficient for meeting SC 2.4.1. Technique H69 addresses the
potential requirement of adding extra headings.

In order to clarify the difference we will reword the description
section in H42. In particular, H42 is not necessarily used to "convey
the structure of the content" (because this may or may not be true)
but is instead used to "provide semantic code for headings in the
content". We will also add information about the benefits that heading
markup can provide and remove the confusing failure-related
