I'm doing this with 'element_type' as the accessor.  I
got this to work with element right off the form tree,
like so:

my $w1	= HTML::Widget->new;
my $f1	= $w1->element('Fieldset', 'top');
my $e1	= $f1->element('Textfield', 'tfone');

is(
     $f1->element_type,
     'Fieldset',
     'Checking element_type accessor'
);  ## PASSED

is(
     $e1->element_type,
     'Textfield',
     'Checking element_type accessor'
); ##FAILED

The second test fails though..  I don't think updating
the element method in HTML::Widget::Element is enough
to set the accessor properly, looks like there is
something to do in HTML::Widget::Container as well,
although I'm still new to the source.  Does anyone
know which package has the element method that gets
called when an element object calls it's element
method?
