Without using an intermediate control, it is complicated, I am not sure
how you can do this.

That's right: at this point you need to use a control for this, and hide it with "display: none".

You can already dispatch events from JavaScript, and we plan to add support for context events (just as you can now on the XForms side with <xxforms:context name="my:control" select="my/control"/>, see: http://www.orbeon.com/ops/doc/reference-xforms-extensions#dispatch-context). When this is done, you will have another option.
