   This appears to me to allow unrestricted MathML content
   to be present as the content of a 'cn' element.  However,
   according to section of the MathML-20031021

the schema is correct here. says

   The cn element may also contain arbitrary presentation markup in its
   content (see Chapter 3 Presentation Markup) so that its presentation
   can be very elaborate.

This does more or less as a side effect allow it to be completely empty,
which probbaly isn't very useful but hard to legislate against: there
are many presentation expressions that you could put there thathave no
visible rendering.
