Re: ACTION-640: clarification to interaction model?

The 4.1 proposed text is fine.

I can see your point on the change to the first two paragraphs, but I still think something more is needed to narrow the scope. The text in 5.3 refers to "all content" and "all other resources". It does not acknowledge that some content might not be coming through an HTTP transaction. That is the root of the problem. We need to remove that "all" qualifier and replace it with something more narrow. Any suggestions as to what? Providing some explanatory text elsewhere doesn't seem to solve the problem.
