engiGetAttrDerivedBN

This call can be used to check if an attribute is defined schema wise in the context of a certain entity. Technically engiGetAttrDerivedBN will transform into the following call

    engiGetAttrDerived(
            entity,
            sdaiGetAttrDefinition(
                    entity,
                    attributeName
                )
        );
