The actual name of the class is TemplateUpdateProcessorFactory and it is possible to optionally drop the UpdateProcessorfactory part. The Template.field specifies a field name as well as a template. The Template.field parameter is multivalued , so , it is possible to add multiple fields or a multivalued field with same name
