Differences
Well tagged PDF:
The 'Art' element in Well-Tagged PDF is used to delineate an article or a self-contained narrative unit within a document. It groups content that belongs together as an independent article.
It should be clearly defined and nested within the structure tree with a consistent role, allowing content extraction and reflow of individual articles.
PDFUA:
In PDF/UA, the 'Art' element marks a distinct article segment, facilitating navigation for users of assistive technologies by grouping related content logically.
