Consistency: If QoS=0, QoS is 0, or QoS is set to 0

I'm only using QoS as an example.

I find it easier to read this style especially if multiple bits impact the logic:

3163 session with a non-zero Session Expiry Interval. It is common to send Request Messages at QoS=0 and

than the other variations.

What the editorial preference? And then consistency should be applied.
