Re: Re: Content Transformatnion Guidelines: Last Call Working Draft ( LC-2085) ( LC-2268 LC-2267)

 Dear Thomas Roessler ,

The Mobile Web Best Practices Working Group has reviewed the comments you
sent [1] on the Last Call Working Draft [2] of the Guidelines for Web
Content Transformation Proxies 1.0 published on 6 Oct 2009. Thank you for
having taken the time to review the document and to send us comments!

The Working Group's response to your comment is included below, and has
been implemented in the new version of the document available at:
http://www.w3.org/TR/2010/WD-ct-guidelines-20100211/.

Please review it carefully and let us know by email at
public-bpwg-comments@w3.org if you agree with it or not before 11 March
2010. In case of disagreement, you are requested to provide a specific
solution for or a path to a consensus with the Working Group. If such a
consensus cannot be achieved, you will be given the opportunity to raise a
formal objection which will then be reviewed by the Director during the
transition of this document to the next stage in the W3C Recommendation
Track.

Thanks,

For the Mobile Web Best Practices Working Group,

Your comment on 4.2.9 Proxy Decision to Transform:
> As a final comment, in the check list at the top of section 4.9.2, the

> > allow it to present the content unaltered;"
> 
> Given that content transformation proxies at times depend on the

Working Group Resolution (LC-2268):
We agree and have updated the bullet point in section 4.2.9 to mention
that use case.

Working Group Resolution (LC-2267):
We take your point, but this document does not specify the internal
operation of transforming proxies so we find it hard to think of anything
useful to say.
