It struck me that D.E. via @class, @data-* and @profile has some similarity with Maciej's idea about D.E. via custom attributes [1]. Here I quote a start tag example of what Maciej had in mind [3]: <div rotating-sphere -webkit-rotating-sphere -moz-rotating-sphere> Maciej's example would be possible via the @profile/@class/@data-* D.E. proposal as well though: <div class="rotating-sphere -webkit-rotating-sphere -moz-rotating-sphere" profile="uri" ></div> So, Maciej, what's your view of Toby's proposal? Personally, My view is that unless your proposal allows authors to make the custom attributes valid, then your proposal will only work for vendors - as only the big browser vendors can afford to recommend un-validating attributes.
