DomainType | Required. MMT_MARKET_BY_PRICE = 8 |
Interactions | Conditional. • InitialImage: true, indicates that an initial image is required. • InterestAfterRefresh: true, indicates that a streaming request is required. • Pause: true, indicates that a pause is required. |

QoS | Optional. Indicates the QoS at which the consumer wants the stream serviced. If both QoS and worstQos are specified, this request can be satisfied by a range of QoS. |

This should only be used on services that claim to support it via the SupportsQosRange item in the Source Directory response (for further details, refer to Section 4.3.1.1). |
