The name attribute in form controls does only one thing:
Identifies how to construct the name-value pairs submitted 
to server. Therefore their "current value" should be unique 
when the form is submitted. They have nothing to do with ID.

Section 12.2.3 refers only to  "A, APPLET, FORM, FRAME, IFRAME, IMG, and MAP." 
none of which is a form control. Due to historical reasons these elements
have a name attribute. This name attribute serves the same purpose of ID 
and is deprecated in favor of ID. This should reduce confusion.
