ISSUE-257 (Is the CT-proxy aware?): Clarification of section 4.1.2 [Content Transformation Guidelines]

http://www.w3.org/2005/MWI/BPWG/Group/track/issues/

Raised by: François Daoust
On product: Content Transformation Guidelines

As discussed a bit between Jo and I as part of ISSUE-255:
http://lists.w3.org/Archives/Public/public-bpwg/2008Jun/0026.html

....the intent of the section 4.1.2 in latest draft is unclear:
http://www.w3.org/2005/MWI/BPWG/Group/TaskForces/CT/editors-drafts/Guidelines/080606#sec-decision-to-transform

Since we dropped all kinds of possibilities for the CT-proxy to advertise, in the request, the fact that it intends to transform the response, having the CT-proxy decide, when it receives a request, whether it's likely to transform the response ends up being a moot point because there's no consequence as far as the guidelines are concerned.

The section should therefore be about "Proxy Forwarding of Request".
That's mostly the case anyway, save the first part that lists heuristics to determine whether it intends to offer transformation services.

Propositions:
1. rename section 4.1.2 to "Proxy Forwarding of Request"

2. drop first bullet list in 4.1.2 about intention "to offer transformation services"

3. amend first bullet in 4.4 on previous interaction with the server with the note on the consistency of user experience that was in 4.1.2.

4. update the sentence "If, as a result of carrying out this analysis the proxy remains unaware of the server's preferences and capabilities it SHOULD" to something like "If, taking into account the result of previous interaction with the server, the proxy remains unaware of the server's preferences and capabilities it SHOULD"

The last point is motivated by the fact that the other previously listed heuristics should not impact the decision of the Proxy to send the unaltered request and then the altered one. Note that CT-proxies may still use whatever heuristics they may want to use to determine if they are "aware" or not.

Francois (realizes he's trying to start a discussion on "awareness", wonders if he should change his nickname to JCVD ;-))
