Default Setting for a Radio Group not activated when Read-Only

Question

I have an Item on a page that is a Yes/No radio group. It is conditional read-only and has a conditional default value. Both the read-only section and the default section use PL/SQL blocks to determine there use. When the read-only condition is true the radio group is grayed out but neither the Yes or No button is checked. It then returns a null value when the page is submitted.

Default is Yes (http://tinypic.com/i39qh4.jpg)
Readonly is true (http://tinypic.com/i39s7p.jpg)
Rendering works fine.
But when the page is submitted, the Yes value doesnt get into session state.
This is because the read-only is implemented by setting disabled=disabled on the radio element.
As per relevant standards (http://www.htmlhelp.com/reference/html40/forms/input.html), disabled form elements are not submitted during a POST operation.
But if it is a readonly item with a default value, you already know the value (you put it there), so why do you need it in session state, just use the default value (hardcoded)
Thanks.
