Is curly brace syntax and OPTIONAL realy enabled in Oracle 11g? (11.1.0.7)

Question

I have just installed Oracle 11g patchset to upgrade from 11.1.0.6 to 11.1.0.7.
Oracle documentation states, that since 11.1.0.7 Curly brace syntax is allowed (http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28397/sdo_rdf_concepts.htm#CIHHDGDI).
When I try to execute following SQL on sample family RDF data, I got an error. Is realy curly brace syntax and OPTIONAL feature enabled in 11.1.0.7?
SQL> SELECT x, y
2 FROM TABLE(SEM_MATCH(
3 '{?x :grandParentOf ?y . ?x rdf:type :Male}',
4 SEM_Models('family'),
5 SEM_Rulebases('RDFS','family_rb'),
6 SEM_ALIASES(SEM_ALIAS('','http://www.example.org/family/')),
7 null));
SELECT x, y
FROM TABLE(SEM_MATCH(
'{?x :grandParentOf ?y . ?x rdf:type :Male}',
SEM_Models('family'),
SEM_Rulebases('RDFS','family_rb'),
SEM_ALIASES(SEM_ALIAS('','http://www.example.org/family/')),
null))

To use this syntax you need to download and install a new Oracle DB semantic technologies patch on top of 11.1.0.7.0:
