1. Most cases just seem to refer to the property name, but others use the style <Name> property. For example:
1088 maximum packet size the client is willing to accept. If the Maximum Packet Size property is not present,
1421 messages are supported. It is a Protocol Error to include the Retain Available property more than once.
1502 Subscription Available property more than once.
This could use a consistency pass.
2. "Property" (1481) below should be "property" or the property name.
1480 The Server uses this value to give additional information to the Client. The Server MUST NOT use this
1481 Property if it would increase the size of the CONNACK packet beyond the Maximum Packet Size
