Ah, gotcha.

I'll agree with that.

You already outline some problems with rel alternate (I snipped them out),  
but rel="alternate" isn't suited regardless. "Alternate" is defined in the  
HTML spec:

"Designates substitute versions for the document in which the link occurs."

In the case of enclosure links "alternate" is not suited, because the  
media file is not a substitute version of the document in which the link  
occurs - it is a substitute version of another link on the document in  
which the link occurs.

The people who are making several versions of videos available right now  
are already grouping using one element or another. Rocketboom.com uses  
<center> to group, but others use other elements (like <p>, <ul> or  
<div>). Adding a class name like you suggest seems to be the easiest
