Good catch. I don't know if this was left from an earlier version of the 
spec but I feel like capital S would be more consistent with the naming 
style. Anyway, I made the change to be consistent with the latest spec.

You've probably seen my e-mail at public-owl-dev about how global 
reflexive properties may have unintentional side effects. For this 
reason, I personally avoid using them and stick with SelfRestriction. 
But I've also created some test cases for owl:ReflexiveProperty. Here is 
one example ontology used to test several different features in OWL 1.1 
including owl:ReflexiveProperty:

Another good catch. Fixed.

I'm not really happy with it but nobody else seems to care about this 
right now so I'm just using owl:minInclusive right now.

There are still some minor issues I'm working on. More testing needs to 
be done for OWL 1.1 features in general. I'd be happy to hear from 
people if they have use cases they would like to share. If everything 
goes smoothly, the final release should be ready really soon (I'm hoping 
sometime next week) which is when it would be safe to do the switch.

Cheers,
