Differences

Well tagged PDF:

The 'WP' element in Well-Tagged PDF denotes the parenthetical characters or markers associated with a Warichu annotation, acting as visual cues.

It should be used in conjunction with Warichu annotations to group fallback punctuation, ensuring visual consistency if the annotation text is not rendered.

PDFUA:

In PDF/UA, the 'WP' element supports accessibility by providing additional contextual markers for Warichu annotations.

It must be tagged appropriately, with any necessary alternative text, to allow assistive technologies to convey its function alongside the main annotation content.
