HTML5.1 Should we forbid nesting form fields in radio groups

I had an action item to articulate a discussion about 5.1 next
regarding nesting form fields in radio groups.

Recently during WCAG evaluations I've been finding quite a few radio groups
with nested form fields.

I have a couple of mock up examples here
http://davidmacd.com/test/form-field-nested-in-radio-list.html

 It is very difficult for screen readers users to navigate this. Let's
assume developers don't want to place the nested elememt below the radio
group either dynamically via show/hide (when the pertinent radio button is
selected) or statically (always visible). Placing an aria-label on the drop
down doesn't seem to help either.

I'd argue it is a very bad UI design to do this and that it should be
redesigned with the nested fields below the radio group. Unfortunately,
many devs seem to like it. Currently, I would fail it in WCAG. Do we need
an explicit failure technique in WCAG or in the HTML 5.1 spec. Is there
something we can do using existing accessibility structures to fix it
(create a positive technique), while keeping the layout.

Cheers,

David MacDonald
