The two concepts - prefetching & enclosures -- are actually different.
 I think these things get somewhat confused because of RSS enclosures.
 An enclosure just says that this thing is part of it.  An enclosure
is a semantic concept.  (It doesn't say to necessaritly prefetch it.)

Now, user agents, in certain contexts, often do in fact prefetch the
enclosures.  (Which is how I belive the confusion came about.)

No.  (See above.)
