Making the changes to the DTD

[Benoit Bezaire <benoit@itedo.com>]

Hi cgmo-webcgm,

  I didn't hear any objections to the suggested DTD changes, so I'm
  going ahead. We said we wanted to publish soon, so ...

  If people don't like the changes, we can always revert back after
  the CD.

  Regards,
