Subject: Re: [mqtt-comment] Subscribription Identifiers with multi-topic subscriptions
We are current outside of a public comment period.
Section 18.104.22.168.2 (Subscription Identifier) deals with this issue:
The Subscription Identifier is associated with any subscription created or modified as the result of this SUBSCRIBE packet. If there is a Subscription Identifier, it is stored with the subscription. If this property is not specified, then the absence of a Subscription Identifier is stored with the subscription.
