  The expansion gets processed when the attribute is processed.  It
can't be earlier, because the attribute doesn't exist.  It can't be
later, because then the *later* expansions wouldn't work.

  i.e.  Foo = "%{User-Name}"
	Bar = "%{Foo}".

  What's "Bar"?  It's not %{User-Name}.

  I don't see why.  That part of the code hasn't changed for a long time.
