user agent accessibility mapping requirements for hgroup added to html 5.1

Hi all,

I have specified user agent accessibility mapping requirements for
hgroup in the HTML spec
in the section detailing user agent requirements for obsolete features [1]

It states:

"The hgroup element does not have Strong native semantics or default
implicit ARIA semantics. User agents must not implement accessibility
layer semantics for the hgroup element that obfuscates or modifies the
semantics

of its children."

relevant commit[3]


This clarification has been prompted by discussion on a hgroup related
firefox bug [2]


please review, after feedback I plan to commit to the HTML5 CR spec.
