Focus on container controls

Focus information is spread around the document in a bit of a haphazard  
way, so I'm (slowly) trying to gather it in "Implementation Requirements  
Common to All Controls"

In any case I have added this rule, and wanted to check we agree.

* If a [[#container-controls|container control]] is given focus, focus  
goes to the first enclosed core control in navigation order that can  
accept focus. If there is no such control, no control has focus.
