-- In PropertyParm, value is a SEQUENCE OF octet string. When sent
-- by an MGC the interpretation is as follows:
-- empty sequence means CHOOSE
-- one element sequence specifies value
-- If the sublist field is not selected, a longer sequence means
-- "choose one of the values" (i.e. value1 OR value2 OR ...)
-- If the sublist field is selected,
-- a sequence with more than one element encodes the value of a
-- list-valued property (i.e. value1 AND value2 AND ...).
-- The relation field may only be selected if the value sequence
-- has length 1. It indicates that the MG has to choose a value
-- for the property. E.g. x > 3 (using the greaterThan
-- value for relation) instructs the MG to choose any value larger
-- than 3 for property x.
-- The range field may only be selected if the value sequence
-- has length 2. It indicates that the MG has to choose a value
-- in the range between the first octet in the value sequence and
-- the trailing octet in the value sequence, including the
-- boundary values.
-- When sent by the MG, only responses to an AuditCapability request
-- may contain multiple values, a range, or a relation field.
