Not necessarily. The logic runs like this: There is lots of alt="" out there. Some of it refers to stuff that doesn't need more text for understanding, and can be effectively treated as presentation. Adding role="presentation" would help distinguish this, IF there is some mechanism where authors who care add role="presentation", while authors who just want to pass a conformance test don't. In either case, I agree with Maciej that the spec should not tell software what not to show - dealing with these situations is messy enough that different heuristics for different users are going to matter for some time (at least until authoring improves, and I don't think that will be soon...) cheers chaals -- Charles McCathieNevile Opera Software, Standards Group je parle français -- hablo español -- jeg lærer norsk http://my.opera.com/chaals Try Opera: http://www.opera.comReceived on Saturday, 22 August 2009 11:46:50 GMT
