With instance(), you can only access instances declared in the current
model. This is what the XForms specification mandates; don't ask me
why :). But we provide an alternate function which lets you access any
instance: xxforms:instance(). It works like instance: you don't need
to specify the model, since you are not allowed to use the same
instance ID even in different models. More on this function (an other
extension functions) at:
