[Pellet-users] Check for no subclass

[Alexander Musidlowski]

Hi,

i think you refer to the sentence "and owl:Nothing is a subclass of
every class". As EquivalentClass is a SubProperty of Subclass
shouldn´t it also return owl:nothing?
In my tests it returns an empty set.
I think the same holds for equivalent and subProperty, doesn´t it?
The specs are nice but i don´t think there are the right documents.
They say what should be returned generally and ideally.
