Read-only properties should not be set

Since they are not settable properties and not input parameters defined by the domain model for the createDocument service, remove the following objects from the example... "cmis:checkinComment" : "this is a new note" "cmis:contentStreamMimeType" : "text/plain" "cmis:contentStreamFileName" : "note.txt" I do think it would be useful to set provide a checkin comment on a document create (especially since the default is to create a major version) and I do think it would be useful for clients to set contentStreamFileName, those should be addressed by separate jira issues.
