ISO, Coga and module two

Hi Folks

ISO approached me about metadata support for COGA. This is really supported
by module 2  (see https://w3c.github.io/personalization-semantics/help/ ).
However as this is a very early draft I though some more clarity, review of
cogas later works etc, would be a good idea.

To help this along I have made a draft at docs.google.com
<https://docs.google.com/document/d/1TDPA3R1Y4hVn4Eq9NlRTZ_hg4cpd_8ZtpWoFiVuF_lk/edit?usp=sharing>
of items that could be supported in content or alternative versions.

such as https://www.w3.org/wiki/WebSchemas/Accessibility



All the best
