A DTE is a holding area which allows a subscriber to attract Guaranteed messages matching a given Topic subscription. Durable means that the subscriber that is bound to the given DTE, does not have to be online to attract matching messages.
This method does not provision the DTE on the appliance. The represented DTE must be first provisioned on the appliance before any use by the API. Applications are able to provision DTEs on the appliance using Provision(IEndpoint, EndpointProperties, Int32, Object) where capability ENDPOINT_MANAGEMENT exists. The name parameter is the name given to the Topic Endpoint when provisioning it on the appliance. Applications can call Provision(IEndpoint, EndpointProperties, Int32, Object) to provision it on the appliance.
DTEs are only supported on appliances with an Assured Delivery Blade (ADB).
