Perhaps the language isn't entirely clear here. I think Kevin's  
intention was along the lines of "the destination is meant to be  
downloaded can cached by the useragent." Kevin?

I don't think your relEnclosure and http://microformats.org/wiki/rel- 
enclosure are that different, they're just explained differently.  
Also, I think they're close enough to be resolved. You want to work
