the main reason probably is that HTML needs to be able to distinguish between ordered and unordered list, in order to create the proper bullets or numbering...

In PDF, all is said and done in this regard - the bullets or numbers or whatever are already part of the page content, no hint needed as to how to generate them. Rather the bullet or numbering is enclosed in a Lbl tag. BTW - this is much more flexible than HTML which may have to use (presentational) CSS hacks where PDF can actually remain more semantic ;-)


Those wishing to give a suitable hint to a tool repurposing the PDF into HTML are encouraged to use the ListNumbering attribute for the given list.
