Evaluating procedures proposal and examples

I've been working on the evaluating procedures proposal write-up that we 
discussed last week, and on a few examples. The content is very rough, 
but I think shows the general shape. I believe this will be on survey 
for the AG next week, but I'd like to continue to improve it if we can. 
This is all reflected in pull 653 
<https://github.com/w3c/silver/pull/653> which includes in particular:

  * A new section on outcome implementation procedures
    <https://raw.githack.com/w3c/silver/evaluating-procedures-proposal/guidelines/index.html#outcome-implementation-procedures>
  * Example 1: Provide help and support (small orgs)
    <https://raw.githack.com/w3c/silver/evaluating-procedures-proposal/examples/outcome-implementation-procedures/example1.html>

  * Example 2: Provide help and support (large orgs)
    <https://raw.githack.com/w3c/silver/evaluating-procedures-proposal/examples/outcome-implementation-procedures/example2.html>
  * Example 3: Plain language
    <https://raw.githack.com/w3c/silver/evaluating-procedures-proposal/examples/outcome-implementation-procedures/example3.html>
  * Example 4: Omnibus procedure for multiple outcomes
    <https://raw.githack.com/w3c/silver/evaluating-procedures-proposal/examples/outcome-implementation-procedures/example4.html>

The content of these examples is very rough and incomplete. I think the 
overall structure proposed works, but the real differentiation between 
examples is in the steps and evaluation procedures. I find that details 
of those goes outside my expertise. I put in "hand-wavey" content to 
suggest the general direction, but I think the examples would be much 
more convincing if that content could be improved. So please review the 
content in that context, but also suggest tangible improvements by email 
or additions to the pull request if you can.
