Marked content

In a PDF document, a portion of content can be marked as a tagged content element. The tagged content feature helps manage the logical structure information of a PDF document and can be used to generate tagged PDF (tagged PDF). Tagged PDFs have standard structure types and properties that facilitate extraction and reuse of page content. For more details on tagged content, see the relevant section of the PDF reference.
