No, that’s a non-sequitur. You asked why we don’t simply assume HTML, CSS, and Javascript and do titling using XMLHttpRequest, or the like. That assumes an *implementation* using HTML. The simple expression needs to express what we need in captioning, independent of the implementation thereof. Why does it need to be a ‘superset’ of anything?
