This object provides info about this row in the form of
an ASCII string, suitable for display purposes. The
intended purpose of this object is to provide an
'agent-specific' explanation as to why the
ctPriClassifyRowStatus for this conceptual row is in
the 'notReady' state. A management station should read
this object and display it to the user in this case.
A conceptual row that does not fall into this category may
simply return a single NULL, but may also provide any useful
info of its choice. A management station may attempt to
display such info if it so chooses, but is under no burden
to do so.
