The example is working, valid XForms. See the reply to Susan Borgrink.

That is exactly what I want.

What I do not understand here is the part of " an xf:select(1) that 
takes its selection choices from one instance and places the result in 
another". Would anyone want to fetch the choices from the input/output 
file, according to some "selected" attribute? That would be redundant in 
the extreme.

I'm sorry to say that fP already has been evaluated (albeit only a short 
time) and discarded as an option for our project since it seems unable 
to display the data in an orderly table. While Chiba looks like

only minimal CSS editing, fP looks like 
If you can provide me with an example of an fP XForms document which 
looks more like the Chiba example, I would be happy to re-evaluate your
