Yes, indeed.

No, that's the point. Crisp tools simply do nothing with them. No  
special treatment and current parser still will work. These are just  
crisp OWL concepts and role symbols.

Exactly, that's has to be done anyway ...

Anyway, I suggest to use standard OWL-DL to encode imperfect  
knowledge. We may later on suggest weather it is better to extend OWL- 
DL (RDFS/RIF/RuleML) or just to propose a CORE ontology about  
representing imperfect knowledge.
