engiGetInstanceAttrTypeBN

Combines sdaiGetAttrDefinition and engiGetInstanceAttrType. Technically engiGetInstanceAttrTypeBN will transform into the following call

    engiGetInstanceAttrType(
            instance,
            sdaiGetAttrDefinition(
                    sdaiGetInstanceType(
                            instance
                        ),
                    attributeName
                )
        );
