If this approach is taken, rather than preempt any possible use of size related values for icons, how about: <link rel="icon" type="application/svg" href="whatwg.svg"> <link rel="icon icon-16 icon-32" type="image/microsoft.vnd.icon" href="whatwg.ico"> <link rel="icon icon-16 icon-32 icon-64 icon-128 icon-256 icon-512" type="image/x-apple-icons" href="whatwg.icns"> <link rel="icon icon-59x60" type="image/png" href="whatwg.png"> Using "icon-*" to indicate square icons and "icon-*-*" to indicate non-square icons would give a specific relationship of it being an icon a specific size for a particular rel value and not be quite so open ended. Scalability is already indicated by the type attribute and could be left to be implied by the use of just plain "icon" without any of the more specific markers. The use of the plain icon keyword on the ones with specific sizes indicated would only be needed for backward compatability with UAs that don't understand the extended forms proposed here.
