And if I want to execute ECMAScript from Java or vice versa or either of 
those from some other language that has easy access to the DOM but can't 
easily evaluate the script string?  It looked to me like SVG was trying 
to really support Java and ECMAScript on an equal footing; was I wrong?

(Not to mention issues like trying to execute a JavaScript 1.2 script 
from inside JavaScript 1.3 and so forth... eval really does not cut it

Very well.  Provide an alternate solution to the use cases this solves, 
then?  URIRequest and eval really don't cut it there.

It does not, for the reason described above.

Again, feel free to propose other solutions to these common use cases...
