[scalaxb]How are repeated child elements mapped to case classes?

sample.scala

case class Person(personsequence1: jp.sf.amateras.scala.util.xsd.PersonSequence1*)

case class PersonSequence1(lang: jp.sf.amateras.scala.util.xsd.Lang)

case class Lang(value: String)

sample.xsd

<?xml version="1.0" encoding="UTF-8"?>

        targetNamespace="http://www.example.org/sample"
