Comment 155 for bug 114441

The only use case the ruby-use-cases document lists as not handled by HTML is the one specifically targeting browsers that don't implement Ruby at all. Are we really going to add two whole elements and so significantly complicate the processing algorithm just to easing the short-term transition pain as we wait for implementations to appear?

(Incidentally, it looks like the markup in some of the examples is missing and has "•" instead. Is that intentional? I'm not really sure what it means, if so.)
