You can use the new xf:duplicate action. It's in XForms 1.1, but is already
supported in a number of implementations.

Just set an instance up as normal for a submission, and then fire the
submission on xforms-ready or xforms-model-construct-done. We use this
technique a lot, and the nice thing is that if the instance that you are
submitting is itself initialised with @src, you can change how you query for
the second lot of instance data. (For example, a user saves some preferences
to a server, and your form first loads those preferences using @src, and
then fires a submission on xforms-ready that retrieves the data relevant to
their saved preferences.)

I've Googled and Babelfished, and I can't work out what you mean -- sorry!
Is it where you are based?
