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. The
 following are descriptions of valid characteristics: You can use
 any combination of attribute specifiers in a single command. Use a
 comma to separate the specifiers. If you do not supply any attribute
 specifier, the command displays all identifiers and their values.
 The following are descriptions of valid counters, identifiers, and
 status attributes:

 COUNTER

 Creation Time

 Specifies the time at which the clerk added this known namespace to
 its cache.

 IDENTIFIERS

 Name

 Specifies an external, human-readable name by which the namespace
 can be identified. If the namespace nickname is unique, the Name
 is the same as the Nickname. Otherwise, the Name is generated by
 appending _n to the nickname for some value of n that makes it
 unique. The Ambiguous attribute is then set true for the known
 namespace.

 NSCTS

 Specifies the creation timestamp of the namespace.

 STATUS ATTRIBUTES

 Ambiguous

 Indicates whether the nickname for this namespace is ambiguous;
 that is, more than one namespace known to this clerk has the same
 nickname. If true, the namespace nickname is ambiguous. If false,
 the namespace nickname is unique.

 Explicit Creation

 Specifies whether the namespace was created by a create command. If
 false, the namespace was created by the clerk itself.

 Nickname

 The name given to the namespace when it was created.
