// acl_comment - "ignore" ACL subject type
//
// This ACL subject is a historical mistake. It has no use in present applications,
// and remains only to support existing keychains with their already-baked item ACLs.
// Do not use this for new applications of ANY kind.
//
// A CommentAclSubject always fails to verify.
// See further (mis-)usage comments in the .cpp.
