This object specifies the minimum interval of time a subscriber
session can remain dangling in order for the system to consider
it a match in the process of executing a subscriber session job.
A 'dangling' subscriber session is one in the PENDING state.
The value '0' cannot be written to an instance of this object.
However, it serves as a convenient value when the column is not
valid.
This value is valid only if the 'danglingDuration' bit of the
corresponding instance of csubJobMatchOtherParams is '1'.
