The following CMIS Query with a JOIN to secondary type 'Folderish' fails to parse in Nuxeo 5.7.2. Should this work or does it require full CMIS 1.1 support which has not yet been implemented?

Query:

curl -u Administrator:Administrator “http://demo.nuxeo.com/nuxeo/atom/cmis/default/query?q=SELECT+d.*+FROM+cmis:document+d+LEFT+OUTER+JOIN+Folderish+f+ON+d.cmis:objectId=f.cmis:objectId+WHERE+d.nuxeo:isVersion=false&searchAllVersions=true&includeRelationships=none”
