for json http://json-schema.org/ seems to be what we would want. then again imho this is mostly candy on top, well for WSDL/SOAP it would be kind of cool especially since WSDL is so painful to deal with. however the below pieces are the more important ones. > ViewBundle specific comment: > The Serializer component supports Normalizers which could be used here to > serialize the form instance into the above format. > > 2) error handling > Then when the for is submitted. Its validated as usually, but on validation > error it would just return the errors. here we again would need to find a sensible format. again for the ViewBundle the "angle" would be a Normalizer that sees that the form has run errors set and in this case it would just serialize the errors (maybe optionally also the API aka 1)). > 3) processing > When the form is valid it would execute the normal logic.
