Karolin,

The first question is how would you like this to be done at the HTTP
level? One way is to use a multipart/form-data with 2 parameters: the
file (as you do now) and the instance. So in XForms, the instance you
submit would look like:

<instance>
<file>...</file>
<employee>...</employee>
</instance>

Inside <employee> you have a serialized version of instance
('employee'). You can populate the value of that element with a
<xforms:setvalue>, using saxon:serialize(instance('employee', 'xml')),
that you run just before doing the submission. Could this work for you?
