I'm reading in the html spec that the INPUT element can have a

associated with a form.
Formally, those attributes are allowed. There's no definition of their
meaning in this context, as far as I can see.
It is difficult to see what "ismap" could possibly mean unless the INPUT
element has type="image", and in that case, by definition, the image
button acts as an image map of a kind anyway: when the form is submitted,
the coordinates of the clicked location are passed in the form data. The
only natural definition for "ismap" here would be the same, wouldn't it?
Regarding "usemap", partly similar considerations apply. If the element
does not have type="image", what image could it possibly be the map's
image? And if it has, then the button effectively acts as a server side
image map anyway. Should a browser override this and use a client side
image map instead, as defined by the MAP element referred to? Hardly.
