How can I get asp.net controls to generate W3c compliant html?

Question

I recently ran some of my ASP pages through "HTML Tidy" validation and found that several warnings were generated due to HTML tags not being properly formed i.e. extra closing tags.On investigation it seems that the ASP Menu control which i am using as the left navigation bar is generating this invalid HTML. It seems that the HTML for this control which Microsoft's automatically generates just isn't HTML compliant.

Has anyone else experienced this?

Does anyone know if there is any way of fixing this?

See Warnings below
