DOM is not HTML, it's a representation of HTML files. HTML doesn't have classes.
Your analogy is bogus. The C preprocessor is defined in the same document as the rest of the language; that's not the case with DOM, HTML and JavaScript. And server side scripts were available outside of Netscape in 1996. -- Shmuel (Seymour J.)

I'm talking about the DOM object instead of DOM (Document Object Model). The "on" event methods meet encapsulation (methods/functions associated to the object) and polymorphism (different object types support the same interfaces). Since HTML is a set of internally predefined classes (e.g. body, input and many more). If HTML ever externalizes classes, then inheritance would become a factor. This assumes Javascript and CSS are not part of the HTML language. By this logic, C++ is actually 2 separate languages (C and C++) but no one ever makes this distinction. Do you consider HTML's '<input onclick="some javascript">' fundamentally different to C++'s 'input::onclick { some C }'? In C++, does C deviate from the C language? What is it that makes you think C++ is a single language but HTML/javascript/CSS are separate unrelated languages other than they don't follow traditional concepts? Up until 2009, JavaScript was not valid outside of HTML.
