Malformed acl rule in acl doc when modifying permissions

on /public I modified permissions for everybody from Viewers to Editors (Read to ReadWrite) and the acl doc was changed to :

@prefix : <#>.
@prefix n0: <http://www.w3.org/ns/auth/acl#>.
@prefix pub: <./>.
@prefix c: </profile/card#>.
@prefix n1: <http://xmlns.com/foaf/0.1/>.

:ControlReadWrite
    a n0:Authorization;
    n0:accessTo pub:;
    n0:agent c:me;
    n0:default pub:;
    n0:mode n0:Control, n0:Read, n0:Write.
:Read a n0:Authorization; n0:accessTo pub:; n0:default pub:; n0:mode n0:Read.

:ReadWrite
    a n0:Authorization;
    n0:accessTo pub:;
    n0:agentClass n1:Agent;
    n0:default pub:;
    n0:mode n0:Read, n0:Write.

As can be seen subject Read has not disapeared and is a malformed acl rule because it does not include any agent

The consequence is not in operation with the actual NSS but it should fail on a validity checker.

Riproduci la modifica delle autorizzazioni su /public da Viewers a Editors e ispeziona il documento ACL generato. Segui il codice che aggiorna le regole ACL e verifica con un agente se l’autorizzazione Read obsoleta viene rimossa o rimane valida. Il lavoro è completato quando il documento risultante supera un verificatore di validità ACL e mantiene le autorizzazioni ReadWrite previste.
