[OASIS Issue Tracker] (MQTT-385) Simple clients skipping properties

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

Ed Briggs commented on MQTT-385:
--------------------------------

I have re-opened this issue because it is not resolved. In my previous comment, I suggested that we might clarify the text. Ken suggested that modification of this text should be considered a CORE not editorial change, and closed the JIRA, and cited an agreement in a prior meeting.  However, there have also been agreements that the various MAX properties(e.g. packet size, etc)  are useless unless universally implemented.   I think there may be a middle ground here in which editorial changes might suffice, and I think we ought to explore that.   If someone closes this again and decides to open up a core JIRA, it would be helpful to have a 'related JIRA' link to sort this out.

> What is the rationale for this exemption -and- how is it interoperable?
> 757 A Client MAY process the Packet without checking the Properties by skipping over the number of bytes
> 758 specified by Property Length. A Client which does not check the Properties MUST NOT make use of any
> 759 Property it has not checked. A Server MUST check all Properties in a Control Packet.
> 760
> 761 Non normative comment
> 762 This exemption for Clients is designed to allow for simple Clients that do not require the
> 763 information sent in Properties. A full function Client should check and use the information in the
> 764 Properties.
