Illustrator :: Can AI CS5 SVG Export Be Customized?

I'm using AI to make graphics for a medical imaging system. Everything's dandy except the .svg files it exports always have this as the XML declaration, the first line:
 
<?xml version="1.0" encoding="utf-8"?>
 
What I want is an explicit standalone pseudo-attribute, like this:
 
<?xml version="1.0" encoding="utf-8" standalone="no"?>
 
The XML spec says standalone defaults to "no" and isn't mandatory, but the parser I'm using (an Object Pascal adaptation of the Anti-Grain Graphics library, which is kinda deep and which I don't yet understand well enough to modify) crashes unless it's explicitly stated. What the value is doesn't seem to matter but it's got to be there.
 
For the time being I preface the parsing with a step that checks the first line, adds the standalone if it's not there, and saves the altered file. It works but it's a seriously ugly kludge. For the production version I can process the files once and leave the kludge out. Still, at least during development it would be nice to be able to tell AI to include it in the first place.
