The FIELD form item type and .val schema file
Form files using the FIELD item type and/or .val attribute definitions must be reviewed.
Starting with version 2.51, the FIELD item type defining abstract fields in
forms, based on .val schema file attributes is deprecated.
Furthermore, any non-I4GL attribute defined in the .val schema file must be
avoided. Reading attributes in the .val is now only supported for compatibility
with I4GL projects.
With Genero, it is recommended to define all form item attributes in the form definition file.
