To use PDF as an example, the reading order of a PDF file is
programatically determined if it is a Tagged PDF file; if the PDF is
not tagged, then heuristics must be used to decide on a reading order.

However, just having a programatically determined reading order is not
sufficient, since it is possible to tag a PDF file in a way that
doesn't reflect its contents logically or to use layout tables to
create HTML files where the source order does not read logically.

The proposal requires both that the reading order be programatically
determined, and that the reading order "make sense".
