Every DECdns entity has attributes, which are pieces or sets of
 data associated with that entity. Characteristics are attributes
 that reflect or affect the operational behavior of an entity. If
 you do not supply any specified attribute, the command displays
 all attributes and their values. You can use any combination of
 specified attributes in any sequence in a single command. Use a
 comma to separate attributes. The following are descriptions of
 valid attributes:

 CHARACTERISTICS

 DNS$ACS

 Specifies the access control set for the directory.

 DNS$AllUpTo

 Indicates the date and time of the last successful skulk on the
 directory. All replicas of the directory are guaranteed to have
 received all updates whose timestamps are less than the value of
 this characteristic.

 DNS$Convergence

 Specifies the degree of consistency among replicas. This attribute's
 value can be one of the following:

 Low            The next skulk distributes all updates that occurred
                since the previous skulk. Skulks occur at least once
                every 24 hours.
 Medium         DECdns attempts to propagate an update to all
                replicas. If the attempt fails, the next scheduled
                skulk makes the replicas consistent. Skulks occur at
                least once every 12 hours.
 High           DECdns attempts to propagate an update to all
                replicas. If the attempt fails (for example, if
                one of the replicas is unavailable), a skulk is
                scheduled for within 1 hour. Background skulks will
                occur at least once every 12 hours. Use this setting
                temporarily and briefly, because it uses extensive
                system resources.

 By default, every directory inherits the convergence setting of its
 parent at creation time. The default setting of the root directory
 is medium.

 DNS$CTS

 Specifies the creation timestamp (CTS) of the directory DECdns.

 DNS$DirectoryVersion

 Specifies the current version of the directory (derived from the
 DNS$Directory
 Version attribute of the clearinghouse in which the directory was
 created). Multiple directory versions are supported in a namespace.

 DNS$InCHName

 Specifies whether a directory or any of its descendants can store
 clearinghouse names. If this value is True, the directory can store
 clearinghouse names. If it is False, the directory cannot store
 clearinghouse names.

 DNS$ParentPointer

 Contains a set of pointers to replicas of this directory's parent in
 the namespace.

 DNS$Replicas

 Specifies the address, creation timestamp (CTS), and name of
 every clearinghouse where a replica of this directory is located.
 This attribute also specifies whether the replica in a particular
 clearinghouse is a master or read-only replica.

 DNS$UpgradeTo

 Controls the upgrading of a directory from one version of DECdns to
 another. By modifying this attribute, you can initiate the upgrading
 of a directory to a newer version of DECdns.

 DNS$UTS

 Specifies the timestamp of the most recent update to an attribute of
 the directory.
