the programming law of orthogonality suggests that you should have two
variables:

  $Group	JUST the group name
  $Page		JUST the page name

and if any code needs the full page name, it can construct it quickly
enough by concatenation.  as long as those two pieces of data are
universally available, any code can build the full page name if it
needs it.

p.s.  in other words, for simplicity, there is *no* need to have a
FullPageName variable or PageName variable hanging around at all
times.  that's just cluttering up the namespace.
