The point was not recursion but collection. XOXO is a fine way to  
express simple collections, or nested ones; eg hGeo in XOXO is a  
sensible form fro waypoints.

hFeed is more about an accumulated series of separate entities, with  
timestamps and authorship.

Nesting a format in itself is as you say not necessarily meaningful.

hAudio in XOXO would be a sequence, or playlist, which is a useful form.

Another form that is useful is a list of timepoints within a piece of  
media - a chapter list or running order. Many podcasts list their  
contents in this way, and being able to represent the scene structure  
of an extended video piece is similarly useful.
