H_F07 Both title and top level headings incorrectly tagged as H1

PDF-F29, FAIL

Use case(s): Headings

Last updated on April 21, 2025

Description

This example demonstrates a failure condition in which both the document’s title and main section headings are all tagged as H1. This is incorrect, as the document’s title is not part of the heading hierarchy.

PDF/UA-1 requires the first heading in a document to be an H1 and that heading levels are not skipped. It allows multiple H1 headings in a document.

If a title is tagged as H1, however, the main section headings must be tagged as H2.
