Actually, I think that the situation is the opposite. The document
object model finally allows you to refer to document elements from
*outside* your document so that you have *less need* to directly mix
scripts and code. Using DOM I can create a client-side program that
takes an XML instance as input and returns XML as output. I can't do
that with JavaScript as it exists today. The JavaScript "model" is
textual replacement (which must, by definition, be "inline"). The DOM
model is structural processing (which can be done "remotely").

I expect that a few years from now this convention of putting markup and
scripting cheek to cheek will have died out. It is just another face of
the logical markup vs. presentational markup war The trend is from
inline to external, just as with presentation.
