Multiple CommercialModelTypes or UseTypes in one deal

When communicating Deals it is crucial that record companies include values that are as precise as possible – especially for UseType and CommerciaModelType. This may involve UseType and CommerciaModelType tags. 

The examples on this page use the syntax of ERN-3. The only difference for ERN-4 would be the order of the subelements of DealTerms.

For example, the way to communicate that one or more Release(s) is available for use in non-interactive streams and on-demand streams for which revenue is generated through adverts, as well as a Download under a subscription service would be: 

<ReleaseDeal>
	<DealReleaseReference>R1</DealReleaseReference>
	<Deal>
		<DealTerms>
			<CommercialModelType>AdvertisementSupportedModel</CommercialModelType>
			<Usage>
				<UseType>NonInteractiveStream</UseType>
				<UseType>OnDemandStream</UseType>
			</Usage>
			<TerritoryCode>Worldwide</TerritoryCode>
			<ValidityPeriod>
				<StartDate>2016-04-25</StartDate>
			</ValidityPeriod>
		</DealTerms>
	</Deal>
	<Deal>
		<DealTerms>
			<CommercialModelType>SubscriptionModel</CommercialModelType>
			<Usage>
				<UseType>Download</UseType>
			</Usage>
			<TerritoryCode>Worldwide</TerritoryCode>
			<ValidityPeriod>
				<StartDate>2016-04-25</StartDate>
			</ValidityPeriod>
		</DealTerms>
	</Deal>
</ReleaseDeal>


If, however, the two CommercialModelTypes have the same UseTypes, the two DealTerms should be collapsed:

<ReleaseDeal>
	<DealReleaseReference>R1</DealReleaseReference>
	<Deal>
		<DealTerms>
			<CommercialModelType>AdvertisementSupportedModel</CommercialModelType>
			<CommercialModelType>SubscriptionModel</CommercialModelType>
			 <Usage>
				<UseType>ConditionalDownload</UseType> 
				<UseType>NonInteractiveStream</UseType>
				<UseType>Download</UseType>
			</Usage>
			<TerritoryCode>Worldwide</TerritoryCode>
			<ValidityPeriod>
				<StartDate>2016-04-25</StartDate>
			</ValidityPeriod>
		</DealTerms>
	</Deal>
</ReleaseDeal>
