I think it's workable. But I prefer the spec to say something like "If the
only child of an <rtc> is an anonymous <rt>, which means that all content
is directly contained by the <rtc>, it spans all the bases." so that we do
not need to complexify the anonymous box generation part, and we won't
apply something on <rt>s but forgot the content directly inside <rtc>s.
Does that make sense?
