This object specifies whether the wild-card option
has been set.
If this object is set to 'true', then the
wild-card option is set and all the FC traffic
will be considered to match the corresponding
multi-field classifier.
If this object is set to 'false', then the
wild-card option is not set.
Setting this object to 'true' in a multi-field
classifier which has other match criteria set is
an error.
