Check out the work package that the Device Independence Working Group calls "Core Presentation Characteristics." http://www.w3.org/2001/di/ However, to go with this we need the dictionary of uses that these characteristics get put to, what the rationale is for the use of these effects. Such as displaying a 'thought' in italic type. 'Italic' is the effect but "unspoken thought" is the rationale. These rationale terms should be used in @class or @role attributes to guide the application of the aforementioned core, cross-device text effects. We have the clear example from Braille[1] that the range of rationales that get given italics in print is different from the range of rationales that get given italics in equally literate use of Braille. So for cross-device use we need the rationale to be articulated, not just the effect in one deliver context. But Ed, I agree with you that isolating a module which is a) a subset of this 'core presentation characteristics' topic, and b) built up from the i18n work on the Character Model[2] is a sensible way to break out the work.
