The tag determines the generated name (5.2.2.5) from the name related attributes.
For example:
>>> import albatross
>>> class Ctx(albatross.SimpleContext):
... def input_add(self, *args):
... print args
...
>>> ctx = Ctx('.')
>>> albatross.Template(ctx, '<magic>', '''
... <al-input type="image" nextpage="m" srcicons/right.gif" whitespace>
... ''').to_html(ctx)
('image', 'nextpage,m', None, 0)
>>> ctx.flush_content()
<input type="image" srcicons/right.gif" name="nextpage,m">
After writing all tag attributes the execution context
input_add() method is called with the arguments; input field
type ('image'), the generated name, None, and a
flag indicating whether or not the list
(5.2.2.4) attribute was present.
