scriptArgs and Applescript

Hello,
I am trying to determine how to pass variables into an InDesign Server Applescript when calling InDesign server via SOAP. I have seen several examples on how to do this with javascript, but nothing with Applescript -- does anyone have ideas or samples on how to accomplish this task?

I am passing some variables with the scriptArgs parameter in the SOAP call, but what is needed in the Applescript to receive and read the passed variables?

Thanks,
Mark
