The low level XML parser would have to accept mixed, and the binding logic
would need to handle unexpected mixed content gracefully in the same way
that the whole system might have to handle <<<<< or any other number of
illegal XML syntax gracefully.  But I don't think that means that an domain
specific specification language must be able to specify that some construct
is mixed.
