Hi,
I have created Dead letter queue for the default broker in my IS.
How can i create dead letter subscription for a particular publishable document type.
I have gone through the documentation, what they have mentioned is
use {hint:DeadLetterOnly=true} hint in filters.
to specify in filters, we need to create a trigger(with Broker docType & Subscribing service).
i.e we have clients(subscriber) to receive data.
but, deadletter subscription purpose is, it has to store the docType when there are no subscribers.
So please give me your suggestions...

Dead letter queue is configured to retain the guaranteed documents published for which no subscription available in broker. If u want to subscribe all documents gone to dead letter queue then u need to subscribe to dead letter queue as given in documentation advantage u can subscribe many topics/ queue using same subscriber if use the hint:deadletterqueue=true
