2.4.5: This should be at Level 1. Descriptions, headings, labels etc are very important for both people who use screen readers and people with cognitive disabilities. Equivalent checkpoints in WCAG 1.0 are at Level AA
Proposed Change:
Move to Level 1
We have added "descriptive" to SC 2.4.2 (formerly 2.4.3) and moved it to level A.
SC 2.4.6 (formerly 2.4.5) has been moved to Level AA. It addresses descriptive headings and labels, which may need to be understood in context. While headings may not have sufficient descriptive power in isolation, when viewed in the context of a structured document, they do have sufficient descriptive power.
