Hello everybody!
I'm pretty new to XForms and doing a project with XForms and eXist, so I have an XML file as a database. The problem I'm having is the following:

My XForms document looks something like this:
[code=xml]
...
<xf:model version="1.0">
<xf:instance id="data-instance" src="data.xml" xmlns="">
<Data>
<FirstName/>...
