/**
* The KRSS2OWLParser differs from the
* {@link org.semanticweb.owlapi.krss1.parser.KRSSOWLParser KRSSOWLParser} that
* it supports an extended KRSS vocabulary available in many reasoning systems.
* For instance, CGIs can be added with help of (implies subclass superclass),
* range, domain, inverse, functinal attribute can be provided for roles. Note
* that DatatypeProperties are not supported within KRSS2. <br>
