This is a 'scratch draft' that is to say forked from the main line of
Editor's draft versions.  It is a strawman rewrite of 6.2 and 7.3 to
make room for host languages to provide built-in semantics
that takes over from ARIA markup where appropriate.

Please read over the draft and see if there is

a) a simpler way to say it that is still correct.
b) anything we missed.
