Benoit,

This sees to imply a certain architecture (ie a cache), which isn't 
mentioned in 5101.

eg, a PSAMP MP might not have a cache, so there wouldn't be anything for 
the MP to expire.

Also with a permanent cache, entries aren't expired - although they're 
exported, they also remain in the cache.

So "expire" works in some cases, though not all.
