Yes, it’s the same selection process, in fact if it weren’t for the need to expose the cues as HTML, <cues> could just be <video> with a different codec.

To enable multiple <cues> is the same as enabling multiple <videos>, and positioning them is the same as positioning <video>, <audio> or even <div>; you can have as many as you want, it's all just CSS. Silvia and Eric worked out the attributes to select between tracks and to enable them; which works essentially the same as a radio group in a form. This works based on the name and kind attributes.

To clarify, do you intend that the resource selection algorithm of <cue>  
should work just like for <audio> and <video> and only select a single  
resource?

If yes, how does one handle multiple text tracks that can be enabled at  
the same time? If each track has a <cue> element, positioning these in a  
sane way seems rather difficult.

If no, please elaborate on what <source> means when it is a child element  
of <cue>.
