Hi Timur,

The problem of not activating client-side, browser-made adaptation seems to be very similar to the problem of announcing that a web page is intended to mobile devices in order not to be "touched" by server-side Content Transformation Proxies. The CT Guidelines spec [1] advocates, among others, the usage of <link rel="alternate" media="handheld"> mechanisms to announce it.

I think W3C needs to provide a unique solution to the problem and not to suggest different mechanisms in different specs.

I'm ccing the BP group mailing list

Best Regards

Asunto: WICD Core 10.0: Intended Layout


WICD Core 10.2 "Style sheet being provided for specific agent classes"
says:

   A user agent that discovers a CSS style sheet, provided for its own
device
   class, should assume the content was created with specific
properties "in
   mind". The agent is then expected to deactivate any custom adaptation
   techniques (for example rendering wide screen content on a narrow
screen)
   and display the intended layout "as is".
   http://www.w3.org/TR/WICD/#intended-layout-1


When creating content for small screen devices, the ability to tell
user agents to _not_ activate any adaptation techniques is
indispensable.

MobileSafari and Opera Mobile support this now - but differently. Both
agents support the  <meta name="viewport" content="...">  element in
HTML as described here:
http://developer.apple.com/documentation/AppleApplications/Reference/SafariWebContent/UsingtheViewport/chapter_4_section_5.html


As a consequence, I request an update to WICD Core 10.2 and 10.3, so
that the desired functionality does not anymore depend on the use of
style sheets, but the meta/viewport element. The existing
specification on developer.apple.com, refers to the iPhone only and it
also does not specify the meta element for use in XHTML. It would be
good to have a w3 rewrite of this functionality.

Since two vendors support the desired behaviour already, two more
fields in the WICD testsuite could go straight from red to green.

Timur
