This PR aims to clarify the section of the protocol which states that the
id
field is optional even though this field is either required or not present as per the type definitions. (Also discussed in #340)At first, I wanted to mention specifically that
Subscribe
,Next
,Error
, andComplete
message types needs to have theid
field. However, the sentence that needs to be clarified is in the "Communication" section which comes before the explanation of the message types. So, I used the term "Messages corresponding to operations" to refer to those message types.Though, I am not sure if this sentence sounds clear enough. I am happy to accept any improvements for wording.
