RAPDF 1.1
Untagged documents
These are documents in which the structural elements (headings, lists, paragraphs, etc.) are absent.
In this case, the document must be thoroughly revised or completely recreated.
The tagging status can be checked in the document properties: "file" menu, then "properties" sub-menu, then "tagged PDF" parameter; when the indication is "no" the document is not tagged.
