> I'd argue that it's still an API, since it's still parsed, interfaced with by the system. Yes, HTML is an API that browsers can interface with. But that interface is on an entirely different level of abstraction from the web application itself. When a web developer writes HTML to be sent to a client in response to some request, they are not making any changes to HTML itself, as a language, and so they are not working on that particular API at all. Rather, they are using that API to develop their own application whose purpose is entirely different from the purpose of HTML. The value they add is not related to solving the problem of exchanging and displaying hypertext documents.
