15. Virtual Field Descriptions

Some fields including in the various Mappers don’t rely on any actual field in the Model (e.g., ListMapper::NAME_ACTIONS or ListMapper::NAME_BATCH).

In order to prevent any side-effects when trying to retrieve the value of this field (which doesn’t exist), the option virtual_field is specified for these fields.

When the template is instantiated, or whenever the value of the field is required, null will be returned without prying on the Model itself.
