And AFAICS, nobody here in this thread has given an example for 
SelfRestrictions, yet. I thought about it yesterday evening for a while, 
but could not come up with any serious example. Well, besides this 
standard toy class of "SelfLovers", wherein property "loves" is thought 
to behave transitively. ;-)

It's easier for me to imagine that antisymmetry and ireflexivity could 
become important, because, in combination with transitivity, I am able 
to more precisely model all kinds of partial orderings between 
instances, like e.g. ancestor relationships between people or events, or 
inclusion relationships like "locatedIn"/"containedIn" between 
geographical regions.

But where is the "killer application" for owl11:SelfRestriction?
