calling exportOMF() Method using ExtendScript

Does anyone have any experience calling this method using ExtendScript? I'm trying to incorporate it into a script but so far have not been able to successfully call it. I'm assuming it needs an argument of the sequence you want to export an OMF from, but so far it keeps returning "bad argument list" whenever I try to call it with something like:

seq = app.project.activeSequence;

app.project.exportOMF(seq);

I've tried using reflect.properties but haven't been able to find anything useful. Can someone point me in the right direction for calling this method, or tell me what arguments it is expecting?

Thanks!
