> Modify Language around use of $ topics
> --------------------------------------
>                 Key: MQTT-233
>                 URL: https://issues.oasis-open.org/browse/MQTT-233
>             Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
>          Issue Type: Improvement
>          Components: futures
>    Affects Versions: 3.1.1
>         Environment: All
>            Reporter: Marco Carrer
>            Priority: Critical
> Section 4.7.2 Topics beginning with $ states 'The Server SHOULD prevent Clients from using such (where 'such' means topics beginning with $) Topic Names to exchange messages with other Clients'.  We think this is a bit restrictive and should not necessarily be strictly enforced by the broker.  
> Instead we would prefer the 'SHOULD' be changed to a 'MAY'. This is consistent with the Non normative comment which states that "Applications cannot use a topic with a leading $ character for their own purposes".
> We would prefer a language that leads broker implementations to may allow the use of $ topic namespaces through configurable options rather block such topics in an hard-coded way.
