so, nothing has changed apparently. W3C is obviously still happy with serving the needs of novarra, opera and the those who want to make a living out of bastardization of content they have no rights too. The question was which heuristics will tell a transcoder whether an (X)HTML page is mobile optimised or not. I am impressed by the stunt you guys performed to demonstrate that the "mobileOptimised" tag added by the content owner in the markup itself is not enough evidence to say that page is meant to be mobile optimised! amazing. "bruce: i agree with you that we shouldn't crown any vendor-specific marker." Bruce, can you look at yourself in the mirror after saying this? do you realise that here you are talking about a "technology" (transcoders, albeit the term "technology" gives them way more honor than they deserve) which replaces the user-agent string to fool web sites? in terms of standards, transcoders are a sewage, you guys have jumped into it with both feet and references (such as yours) to an inexistent concept of purity will not keep you immaculate. They'll just offer evidence of how ruthlessly opera is exploiting W3C for its objectives. "tom: Agree, this is saying IE Mobile shouldn't transform, but not sure that this could be extended to other browsers not transforming." But it certainly can be extended to transcoders to let them know they should not transcode. Of course, I am no longer expecting you to acknowledge self-evidence, Tom. Do you still go around claiming that you represent developers of some sort? "<SeanP> I agree that we should avoid vendor markup" of course. Sean, I deeply admire your perseverance. "<jo> PORPOSED RESOLUTION: Adopt the MS specific <meta name="MobileOptimized" content="NNN"> as mandatory evidence of mobile content <jo> -1" So much for .Mobi standing by the side of developers, Jo.
