// (e.g. abstract role, owning tenant, owning group, etc) of the ACE. If this were not the case, then the AclProbe would need
// to reproduce code from the SecurityManager, to be able to decide beforehand, whether decideable access condtions
// (e.g. specific tenant, specific user) will match or not.
//
// The "non-decideable" here refers to the information context of the AclExpander, which is lacking some information
// available during normal SecurityManager access rights querying.
// For decideable access conditons (e.g. specific tenant or specific group), the created SecurityToken
// is not guaranteed to match, therefore the AccessTypeStatistics returned by Acl.GetAccessTypes are used to filter out these cases.
//
// One could also try to remove these entries by removing all AclExpansionEntry|s which are identical to another AclExpansionEntry,
// apart from having more restrictive AccessConditions; note however that such "double" entries can also come from ACEs which are
// being shadowed by a 2nd, less restrictive ACE.
//
// Note also that it does not suffice to get the access types for the current ACE only, since these rights might be denied
// by another matching ACE in the current ACL (deny rights always win).
