To allow a single form to be included on a screen multiple times, and for a collective submission from those forms to be handled by a service, it is necessary to ensure each form input can be rendered with a unique name.
The name attribute of the rendered HTML form input is rendered according to the parameterName of a field in the form widget.
To allow generation of unique field parameterNames we can use the FlexibleStringExpander type.
