availabilityStatus	Availability status of the messaging entity.
deadLetteringOnFilterEvaluationExceptions	Determines how the Service Bus handles a message that causes an exception during a subscription’s filter evaluation. If the value is set to true, the message that caused the exception will be moved to the subscription’s dead-letter sub-queue. Otherwise, it will be discarded. By default this parameter is set to true, allowing the user a chance to investigate the cause of the exception. It can occur from a malformed message or some incorrect assumptions being made in the filter about the form of the message. Settable only at topic creation time.
deadLetteringOnMessageExpiration	If it is enabled and a message expires, the Service Bus moves the message from the queue into the subscription’s dead-letter sub-queue. If disabled, message will be permanently deleted from the subscription’s main queue. Settable only at subscription creation time.
defaultMessageTimeToLive	Determines how long a message lives in the subscription. Based on whether dead-lettering is enabled, a message whose TTL has expired will either be moved to the subscription’s associated DeadLtterQueue or permanently deleted. This is to be specified in ISO-8601 duration format such as "PT1M" for 1 minute, "PT5S" for 5 seconds. More on ISO-8601 duration format: https://en.wikipedia.org/wiki/ISO_8601#Durations
enableBatchedOperations	Specifies if batched operations should be allowed.
