not content accessibility like alt-text or color contrast.
PDF Structure Tree (HTML-like view)
Tip: Type 'h7', 'h8', or 'h9' to find invalid heading levels
PDF Role Mappings (RoleMap)
What is this? The RoleMap defines custom roles (like H7, H8, H9) and how they map to standard PDF roles.
Some of these custom roles might be defined but never actually used in the document structure.
