9.3.38.  Building Name

   The Building Name attribute type specifies the name of the building
   where an organisation or organisational unit is based.

9.3.39.  DSA Quality

   The DSA Quality attribute type specifies the purported quality of a
   DSA.  It allows a DSA manager to indicate the expected level of
   availability of the DSA. See [8] for details of the syntax.

9.3.40.  Single Level Quality

   The Single Level Quality attribute type specifies the purported data
   quality at the level immediately below in the DIT.  See [8] for
   details of the syntax.

9.3.41.  Subtree Minimum Quality

   The Subtree Minimum Quality attribute type specifies the purported
   minimum data quality for a DIT subtree.  See [8] for more discussion
   and details of the syntax.

     subtreeMinimumQuality ATTRIBUTE
             WITH ATTRIBUTE-SYNTAX DataQualitySyntax

9.3.42.  Subtree Maximum Quality

   The Subtree Maximum Quality attribute type specifies the purported
   maximum data quality for a DIT subtree.  See [8] for more discussion
   and details of the syntax.

             WITH ATTRIBUTE-SYNTAX DataQualitySyntax

     ::= {pilotAttributeType 52}

9.3.43.  Personal Signature

   The Personal Signature attribute type allows for a representation of
   a person's signature.  This should be encoded in G3 fax as explained
   in recommendation T.4, with an ASN.1 wrapper to make it compatible
   with an X.400 BodyPart as defined in X.420.

     ::= {pilotAttributeType 53}

9.3.44.  DIT Redirect

   The DIT Redirect attribute type is used to indicate that the object
   described by one entry now has a newer entry in the DIT.  The entry
   containing the redirection attribute should be expired after a
   suitable grace period.  This attribute may be used when an individual
   changes his/her place of work, and thus acquires a new organisational
   DN.

             distinguishedNameSyntax
     ::= {pilotAttributeType 54}

9.3.45.  Audio

   The Audio attribute type allows the storing of sounds in the
   Directory.  The attribute uses a u-law encoded sound file as used by
   the "play" utility on a Sun 4.  This is an interim format.

     audio ATTRIBUTE
         WITH ATTRIBUTE-SYNTAX
             Audio
         (SIZE (1 .. ub-audio))

9.3.46.  Publisher of Document


   The Publisher of Document attribute is the person and/or organization
   that published a document.
