You're correct, it does not.  There's a de-facto standard, not a de-jure one.

I want to dynamically execute the script at http://foo at runtime.  Using 
language-dependent mechanisms in ECMAScript I have to somehow load the data into 
a string (dealing with character encodings in the process) and then call eval() 
on it?  Using a <script> node, I just set the src attribute and insert the node.

This is a relatively common use case on the web, especially for working around 
UA bugs by executing slightly different scripts based on UA-sniffing or 
object-sniffing (though most pages use document.write() instead of creating 
nodes via DOM, the concept is the same and document.write() is not available in 
SVG).

Not necessarily.  See the algorithm described in my last response to Jim.
