If annotations are meaningless (as some people claim) then adding 
annotations does not change the meaning, and a reasoning engine that 
adds an annotation e.g.

   rdfs:comment "The reasoning engine loaded this at 6.34 pm" .

then so be it.

It is at least arguable - if people really want that, then I would like 
that to be clear.
