Match of structural elements
If structural elements between the document and the AI-assisted check do not match, this may indicate incorrect tagging.
Example: The AI-assisted check detects a heading (H), but the document contains a paragraph (P) element in the same place.
Detailed explanation
The AI-assisted check has semantically identified a region in the document for which a tag exists in the PDF. If the AI tag and the document tag do not match, PAC 2026 displays an error or a warning.
