Given that there are valid use cases for submitting values of elements 
that have a disabled resp. readonly behaviour in the UI: Would it do any 
_harm_ to allow @readonly to checkboxes and radio buttons? I assume this 
would be easy and possible without breaking existing content. Submitting 
disabled elements, OTOH, looks to me like an impossible change, as it 
would likely break existing content.
