Error Message Feedback

Validating 

I have a page that uses a group of radio buttons. I specified both name="something" and id="something" on all 5 of the radio buttons, each with a different value="something" attribute. 

The validator says the second radio button's id attribute is invalid because that id has already been assigned to another element. I feel that this is incorrect because all the radio buttons should have the same name/id field and different value fields.
