Thanks for the input on the options; I'm not sure how best
to do this survey...

I chose options like "Yes, but only if changes are made..." because
I know what action to take when someone chooses them.

I don't know what the editors or the WG should do differently
based on a reply of "Disagree" vs "Strongly Disagree".

I'd also like the process to be somewhat iterative, but lots
of "yes, as stated" responses only mean something if they
all refer to the same version of the text.
