Differences
Well tagged PDF:
The 'LBody' element in Well-Tagged PDF serves as a container for the main content of a list, grouping all list items together.
It should be used to enclose the 'LI' elements within a list, ensuring that the overall list structure is maintained for content extraction and reflow.
PDFUA:
In PDF/UA, the 'LBody' element supports accessibility by organizing the body of a list, allowing assistive technologies to navigate the list as a coherent unit.
It must be properly tagged and associated with the list container to preserve the logical reading order of list items.
