I don't think vertical terms are applicable. Since the element structures of
both forms are the same, I don't think there's vertical motion involved at all.

It would seem very odd to me to say that global changes of approximately

   <!--\([^-->]\)/-->    to    <!--*\1*-->


   <?\([^>]\)>           to    <?\1?>

are "down-translation". They seem purely horizontal; certainly none of the
real information has changed; only the syntactic details of its
representation. Certainly we wouldn't call re-vamping an SGML file to use a
new delimiter set "down" or "up" translation; and that's all that's really
going on here (the only difference being a clearl trivial one, that SGML
doesn't presently let us change COMO and COMC separately).
