JSON handling in XForms

I've just returned from XML Prague conference. It was really inspiring time=
..

I'm happy XForms user with Orbeon implementation. For me it the best MVC fr=
amework ever seen. I'm waiting for further development the standard.

One of the planned features I consider promising is support for JSON instan=
ces. I have two suggestions in that topic:
1. When XForms would accept JSON models I think that instance (beside DOM a=
ccess) should be available for Javascript as JSON. Usage of instances would=
 be more natural.
2. As far I understood there is a plan to define own mapping between JSON a=
nd XML. In my opinion when XForms world is opening for other formats we may=
 enforce users with customization of the mapping. There may be supported se=
veral options of mapping similar as it is organized for XML and text in XSL=
T / XQuery (XSLT and XQuery Serialization 3.0). I would suggest to move map=
ping issues out of a XForms core and define separate document with possible=
 mapping options. It would also be natural way to add other data formats as=
 YAML or SDL with its own mapping options. Vendors would have clear point o=
f extending the standard.
