http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Oct/0051.html



Following items are triggered by a discussion with Eduardo on the list:
  http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Oct/0040.html

Bullet points quickly attempt to summarize some of the ideas exchanged. 
Please refer to the emails for a more accurate description.
The document extracts are based on previous drafts, but are still valid 
I think.


5. Unclear form encoding must be preserved for the server
-----
http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Oct/0045.html
... Search for "2. Matching the capabilities of the user agent is necessary"

- Current wording makes it unclear that we do not envision that a server 
may receive an encoding different from the one it expects when a form is 
submitted
- Proposal: clarify the text along the lines of what we had in a 
previous draft:
  "Proxies should not alter HTTP requests unless: [...]
     2. an unaltered request body is not consistent with the origin
server's requirements in respect of Internet content type or character
encoding (as may happen, for example, if the proxy has transformed an
HTML form that results in this request);"


6. Character encoding
-----
http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Oct/0043.html

- changing character encoding is not reliable, problematic when there's 
a form involved (on-line orders, banking, e-mail, timetable).
- changing the encoding to another one that is also supported by the 
client is not forbidden.


7. User experience
-----
http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Oct/0046.html

- algorithm proposed to precise what "improving the user experience" may 
mean from a technological point of view based on HTTP headers, UAProf, 
and DDR, and priorities among capabilities.
- cannot and does not attempt to cover everything.
- points of disagreement on the details
- we resolved to leave this out of scope


8. Keep it dry
-----
- Normative statements must be testable.
- Focus on the statements, leave ambiguous statements out of the spec.
- Either we define precise algorithms based on heuristics, either we 
stay silent. If we can't define heuristics, then remove feel-good 
sentences altogether.
- In short, don't mention something if we don't address it completely

Examples:
- "A proxy SHOULD strive for the best possible user experience that the 
user agent supports"... not good.
- "It SHOULD only alter the format, layout, dimensions etc. to match the 
specific capabilities of the user agent"... what are we trying to say?

- On the other hand, we could come up with a full appendix (?) on common 
dangers associated with re-structuring:
http://lists.w3.org/Archives/Public/public-bpwg-ct/2008Oct/0046.html
(end of the email).


9. Capability negociation on the client side
-----
- not mentioned in Scope for Future Work
- add a reference to CC/PP?
