How to remove span tag from WebControl when rendered

Question

When using an ASP.NET CheckBox (and in out case, inherited from a CheckBox) it renders a span around the checkbox input control, this span control

Answer 1

I just tried this on a test page and I'm not getting the around my CheckBox controls... are you sure it's the CheckBox that's rendering this? Is it conditional?

UPDATE: OK, it appears to be conditional on whether or not the CheckBox has extra attributes, including a CssClass setting... or a "disabled" attribute.
