Yes, that would be a problem for ecmascript, though we could add a sentence making it clear that whatever the transformation link maps to must be capable of being used client-side, and that it's the responsibility of whoever uses the transform to make sure it is. I think DanC mentioned the SIMILE project implemented GRDDL using Javascript - but I myself never have personally made a javascript GRDDL. I assume DanC is talking about one or more of the works here [1] and he can answer any further questions regards an ecmascript example. Security concerns should be addressed more thoroughly at some point. Any ideas?
