Master Table, Update to Delete Options

// Nashorn Script (engine type: 1)
// 
// Notes:
// It is also possible to delete multiple ID-Labels in bulk
// Name of created file are "Foo.xml" and "Foo-YYYYMMDDHHMM.xml"
// When [Service Task (Choice Update)] is placed downstream
// - add Select-Type data item and refer to the ID-list and the Label-list
// - https://support.questetra.com/bpmn-icons/service-task-choices-update/
// - https://questetra.zendesk.com/hc/en-us/articles/360002260151-M208
// - M319: Register an Options-XML file to which the Process Model Definitions Refer
// - https://questetra.zendesk.com/hc/en-us/articles/360002262551-M319
// 
// Notes(ja):
// 複数のID-Labelをまとめて削除することも可能です
// 生成されるファイル名は "Foo.xml" および "Foo-YYYYMMDDHHMM.xml" となります
// 下流に［サービスタスク（選択肢マスタ更新）］を配置する場合
// - 別途、選択肢型データを定義し、ID一覧とLabel一覧を参照させます
