> For example, (one of) the real reason we want identifiers is that we want something that does not change with topology locations to identify mobile communication end point, which functions that cannot be carried by IP addresses. Since (I believe) we all have consensus on this function, we can at least agree that identifier is topology-independent label that identifies a communication end point. 

Exactly.

So to extend the definition to be specific. The identifier is used for a host stack transport connection. Its the “thing” (the arguments) you pass to connect(), bind(), sendto(), etc, socket API calls. And what you “get back” from gethostbyname().
