Will code for consuming web services created in Notes 8 run on a Notes 7 client or server?

I need to add functionality to consume a web service to a Notes application. I see how to produce the LS code using version 8 of designer. Does anyone know if I can run the code on earlier versions of Notes/Domino? I’m looking to run it on Domino server version 7.

I assume I would have to copy the lsxsd.lss file to the v7 server to make this work.

thanks in advance!
