[Bug 25003] modify required heading mappings to reflect reality

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25003

--- Comment #30 from Rich Schwerdtfeger <schwer@us.ibm.com> ---
I think the algorithm is suffering from a more serious issue in that it is not
taking into account user context within the page resulting of the use of
landmarks whether they be native HTML elements defined in terms of WAI-ARIA
landmarks or WAI-ARIA landmarks themselves. 

The outline algorithm needs to have a reset in each of these context. IOW you
need to start at the highest heading level in these regions and work your way
through the content contained within the landmark. 

You cannot have an accurate algorithm to produce a TOC if involves computation
across landmark regions vs. within those regions. 

To do this work I believe it should be done for HTML 5.1 or later as there is
not enough runway.
