The TScSFTPACEItem class is a descendant of the TScCollectionItem class.
ACL (Access Control List) attribute (taken from NFS Version 4 Protocol [RFC3010]) is an array of access control entries (ACE). There are various access control entry types. The server is able to communicate which ACE types are supported by returning the appropriate value within the aclsupport attribute.
TScSFTPACEItem holds the parameters of the ACE attribute.
