 Great discussion. It's not interoperability we're talking about, as that's taken care of by XML. It's not portability of code that we're talking about either: code written to an interface in Java is not portable to C in the way that the same interface may facilitate portability from architecture to architecture in C. Rather it's the programmer's ability to contribute regardless of the language being used. Standardizing an API such as DOM across different languages is a nice goal. When I see a few lines of XML traversing code written in Ruby using DOM I immediately know what it's doing despite the fact that I've never coded a line of Ruby in my life. The reality is practically any API that standardizes something as complicated as what DOM attempts is going to have to be shoehorned to fit into the worldview presented by many modern languages. But the DOM will always be familiar to the programmer. Practically everyone can agree that is a Good Thing (unless you're going to start arguing that the monopolization stifles innovation or rather the adoption of new innovations, but that's off topic).
