  As a tool vendor (site testing), we'd also like clarification on
  this issue - at the moment we would flag the second example under
  H42 as an error based on the principle of importance:

   "A h2 is less important than an h1, so how can it come ABOVE it in
    the hierarchy?").

  This also ties in with the HTML5 outline algorithm, which is another
  tricky detail in this puzzle.
