  I do not know XSD, but I guess that the above can already be
  done today, by explicitly allowing this element for every
  element (repeatedly for each element).

  So the only problem of the OP might be that this has to be
  repeated, but this can be eliminated by generating the XSD
  from a program or using a preprocessor. I mean, who still
  writes his XSD manually, today? (seriously; I don't know,
  because I have no experience with XSD.)

  One even might consider to write a tool that translates an
  SGML-DTD to the best XSD-approximation, which would include
  this capability.
