[keycloak-user] Fwd: Documentation question

I am trying to understand this sentence from section 2.2.1 of the User Guide: "The role mappings contained within the token are the union between the set of user role mappings and the permission scope of the application/oauth client." See: http://docs.jboss.org/keycloak/docs/1.0-rc-1/userguide/html/Overview.html... Should this perhaps read the "intersection between" rather than the "union between"? I guess I am trying to understand if it is the union of the two sets or the intersection between the two sets. My guess, based on the rest of the paragraph, is that it is the intersection between the two sets. Thanks, Alarik
