Specifies the collection of custom criteria that are part of the
rule of a FirstPartyAudienceSegment.
Once the FirstPartyAudienceSegment is updated or modified with custom
criteria, the server may return a normalized, but equivalent
representation of the custom criteria rule.
customCriteriaRulewill have
up to three levels including itself.
