 From IRC:
 > I think "Shortcodes do not contain other shortcodes." is wrong

 To be completely precise, the ']' character is never allowed inside of a
 shortcode tag, so by extrapolation there is no way to put a raw tag within
 a tag.  Between tags, almost anything is allowed.

 If you'd like me to research the technical implications of allowing the
 '[' character inside of a shortcode, I could entertain that thought.  But
 that sort of thing could take a couple weeks given my schedule.
