Silver Requirements (high level draft)

All,

We've put together a high level draft of a Silver Requirements document
<https://docs.google.com/document/d/15F4KuNXYK5q2rOgb4ktHiJQMQpAEL9EetARpMU3vD_A/edit>
 (HTML version
<https://docs.google.com/document/d/e/2PACX-1vQwFWjpW-onA9hNb2L_U-jLppulk9cQNsttUdQFnEK9KkGNqoj1Hfc3c4kV1_JohqmCJXBVtZ3RaYAq/pub>),
which we'll send to the overall Accessibility Guidelines Working Group in a
couple of weeks. We still have several outstanding comment threads in there
(largely around needed rewording and simplification of sentence structure),
but please have a look through and add your thoughts or suggestions! Feel
free to comment directly in the document or email

A couple prompts:

   - Does this document make the requirements clear?
   - Did we leave anything out that we should explicitly speak to in this
   requirements document?

For other examples, see:

   - WCAG 2.1's Requirements Document
   <https://w3c.github.io/wcag21/requirements/>
   - WCAG 2.0's Requirements Document
   <https://www.w3.org/TR/2006/NOTE-wcag2-req-20060425/>
   - A search of W3C of Requirements documents
   <https://www.w3.org/TR/?title=requirements>

We'll create a more detailed version later on, once we've all agreed on the
higher level points here. Then, we'll go into a little more detail about
our plans on how to meet these goals and more explicitly what each
requirement means.

Much appreciated!

Shawn
