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.
