I have now looked them up and was somewhat disappointed with the result.
They do not seem to help us much further, but for what it is worth, here
they are.
X.500 Directory Attributes for Device:
commonName text string
A common name specifies an identifier of an object. A common name is not a
directory name; it is a (possibly ambiguous) name by which the object is
commonly known in some limited scope (such as an organization) and conforms
to the naming conventions of the country or culture with which it is
asociated.
description text string
The description attribute type specifies text which describes the
associated object.
localityName text string
The locality name attribute type specifies a locality. When used as a
component of a directory name, it identifies a geographical area or
locality in which the named object is physically located or with which it
is associated in some other important way.
organizationName text string
The organization name attribute type specifies an organization. When used
as a component of a directory name it identifies an organization with which
the named object is affiliated.
organizationalUnitName text string
The organizational unit name attribute type specifies an organizational
unit. When used as a component of a directory name it identifies an
organizational unit with which the named object is affiliated. The
designated organizational unit is understood to be part an organization
designated by an organization name attribute. It follows that if an
organizational unit name attribute is used in a directory name, it must be
associated with an organization name attribute.
owner distinguished name
The owner attribute type specifies the name of some object which has some
responsibility for the associated object.
seeAlso distinguished name
The see also attribute type specifies names of other directory objects
which may be other aspects (in some sense) of the same real world object.
serialNumber text string
The serial number specifies an identifier, the serial number of the device.
