Guideline 4.1 (use-spec) Issue Summary

Attached is my summary of issues related to guideline 4.1. Most of the 
issues that remain seem to be intertwined with our decisions around 
baseline and guideline 1.3. We have received mixed feedback recommending 
that we both strengthen and weaken the current level 1 requirement to 
pass validity tests and use elements and attributes as defined in the spec.

At this point, I'm interested in feedback about how people feel about 
the consequences of strengthening and or weakening this guideline based 
on the proposals I've made under issue #888.

To facilitate discussion, I think it would be helpful to have a more 
complete list of examples where it is particularly important that 
authors be allowed to violate a spec for backward compatibility or 
compatibility with AT as well as examples of cases where the 
consequences of spec violations negatively impact end users.

All the best,

-Ben
