Minor addition to this point. Usually, an XForms form contain a defaul
'instance' data which is referenced by simple expressions like
'/customer/name', but you are allowed to use multiple 'instance' data
objects and you can reference particular 'instance' using instance()
function, e.g.:
The instance:<xforms:instance xmlns="" id="orderform">
<orderForm>
<shipTo>
<firstName>John</firstName>
</shipTo>
</orderForm>
</xforms:instance>
and the reference:ref="instance('orderform')/shipTo/firstName"
The default instance in case of XMLForms is the underlying Form object, so
this will require support for multiple instances.As for the function in
referencing expression: it should not be much difficult as XMLForms uses
JXPath to retrieve values and it's quite easy to add extension functions to
it.
