This is why @replace="instance" / @instance="x" was added to
xf:submission; an XForms processor will replace the current form if
you have @replace="all" or you don't have a @replace attribute.

Now I'm very confused...so you must be using XForms in some form or
another. What processor are you using?

If you are trying to get a 'subform' effect, then I would let
submission run its course, and at the end you will have an instance.
Then use the DOM methods on xf:model to get the instance document as a
DOM, and then copy that into your div. Of course, if the returned data
contains XForms then you'll need your XForms processor to be able to
cope with reparsing, which a server-side processor is unlikely to be
able to do. (Can't have it all your own way, Erik. :)

I can't say, since I don't know what problem you are trying to solve.
You could help everyone if you say what XForms processor you are
using, since then we could tell whether you really, really must use
XMLHttpRequest, or whether you are merely trying to achieve the same
effect as an Ajax form that performs some kind of incremental loading.
