It actually turns out that initializing to non-null values tends to get
you in trouble in containers that recycle tag instances -- we really need
to go through and rip that out (as well as the tendency to modify the
specified attribute values during doStartTag() or doEndTag(), which will
cause nothing but grief with optimizing page compilers.
