H_06 Subtitle correctly tagged

PDF123, PASS

Use case(s): Headings

Last updated on April 21, 2025

Description

The objective of this technique is to show how to tag a document’s title and subtitle separate from the document’s heading hierarchy.

In this example, the title is tagged with a Title tag role mapped to P. The subtitle is tagged with a custom "Subtitle" tag, also role mapped to P.

NOTE: PDF 2.0 formalizes the Title tag, accordingly, reader software that supports PDF 2.0 will handle Title correctly without role mapping.
