No, it's not equivalent. The need for 'all' is to do anything other
than digits. :) Also it's being used currently for EPUB.

Yes. The 'all' value needs to know what element set it, and inheriting
it confuses the issue. The 'digits' value needs to inherit to work
properly.

It's been an open issue for awhile now. We never resolved on it.
