CMIS 1.1 createType

CMIS 1.1 give the ability to manage type definition for adding property of a cmis:document (for example).

However when I want to add a new one Modeshape throw this exception:

14:49:27,489 INFO [org.apache.cxf.phase.PhaseInterceptorChain] (default task-37) Application

{http://webservices.impl.server.opencmis.chemistry.apache.org/}

RepositoryServiceService#

{http://docs.oasis-open.org/ns/cmis/ws/200908/}

createType has thrown exception, unwinding now: org.apache.chemistry.opencmis.commons.impl.jaxb.CmisException: Not supported!

Can you implements it ?

Thanks by advance.
