Hmm.  FOLDED doesn't seem to say anything about foldability, though, only if 
the item is currently folded.

This was my initial thought also - wouldn't it make more sense to have an 
enclosing <FOLDED> tag (or something like that), with an ALT attribute for 
the text to use when folded?  (Or TEXT, TITLE, whatever.)  It seems that if 
the leap is going to be made to expandable/compressible sections of HTML, it 
should not be limited to just ULs.
