Be aware that we are planning on removing the alternative script syntax from the spec. There are a lot of hidden gotchas. At the XMPP Summit, we realized that it hadn't been sufficiently specced and should never have been added to a mature XEP anyway. I think the real solution is to implement your cross domain support with window.name tunneling from a hidden iframe. I'll work up an example of this soon. jack.
