[NTG-context] Support for FormCalc ?

[luigi scarso]

> It seems that Designer open only forms; I will investigate it.
I put a test in
http://www.logosrl.it/context/test/xfa/s2.pdf

It was made from s2.xdp with Designer;
it was  uncompressed with pdftk.

I try to replicate it with s2-0001.tex,
but I have a problem: I don'know how to to group fields
Briefly,I have
subform modulo1
  subform unnamed
    field Campo1
    field Campo2
    field  Somma
Ie modulo1 contains unnamed which in turn contains Campo1,Campo2,Somma .

But with context I have made 3 distinct groups
field Campo1
field Campo2
field  Somma
and this is not what I need.
