Content of cmis.cnd looks strange. I wonder why its required?
[mix:cmis]
    -cmis:objectId - Can we use node id?
    -cmis:name - Can we use node name?
    -cmis:baseTypeId  - Can we use nt:file vs nt:folder for this to map to CMIS base type?
    -cmis:objectTypeId - Can we use primaryTypeId?
