Comment:

4) Section 4.3.6

The proposed heuristics seem to fail completely for i-mode sites, because:
a) i-Mode sites often do not have peculiar URL distinguishing them
from (non-mobile) sites, and in any case the prefix imode.* is not
included in the list of URI patterns to check for.
b) i-Mode sites return mostly their content as text/html.
c) i-Mode sites do not include a DOCTYPE.
d) The markup for i-Mode does not cater for the utilization of the
link element as proposed in the draft, which is therefore not included
in i-Mode content.
e) i-Mode servers do not have much use for the "no-transform"
directive, and hence do not necessarily implement it.

WG Notes: See: http://www.w3.org/2008/10/20-bpwg-minutes.html#item23 and: http://www.w3.org/2008/10/20-bpwg-minutes.html#item28 Final resolutions: - Remove examples of heuristics from the main run of text and include Appendices to list in a *non-endorsed* way lists of stuff that other people have used but are No-endorsed by us, and did I mentionthat they are not endorsed - Ref LC-2022 resolve partial, we agree that this was not included and have added it as a non-endorsed heuristic in the relevant appendix

Resolution: i-Mode DOCTYPEs were added to the list of DOCTYPEs associated with mobile Content: http://www.w3.org/TR/2009/WD-ct-guidelines-20091006/Overview.html#sec-Mobile-DOCTYPES
