UA Technique Tag:

Matterhorn Protocol:
01-006, 14-001, 14-002, 14-003
WCAG 2.2 Success Criteria:
1.3.1
Structure Types:
H (PDF/UA-1 - Heading with level deduced from tag structure), H1-H6 (1.x - Headings with specified levels)
Description
This describes a failure condition in which a heading level is skipped. Even though the second heading visually appears to be a third-level heading, PDF/UA-1 prohibits skipping heading levels, to ensure a navigable document. In this case the tags use H1 followed by H3, so the heading level H2 ist skipped.
