Correct dissociation of nssets and keysets using update_domain in fred-client

Suppose this: update_domain guerra.cr NULL NULL NULL (NULL GUERRA-CR-K NULL) This example adds keyset GUERRA-CR-K to domain guerra.cr. Now lets try to dissociate that keyset: update_domain guerra.cr NULL NULL NULL (NULL () NULL) It does not work. Notice that I don't use NULL which, in that context does not touch the keyset entry. () should mean no keyset, right?. The same applies to dissociating an nsset making the domain a reserved one. For example: update_domain guerra.cr.NULL NULL NULL (() NULL NULL) Best regards.
