JAXB可以生成ArrayList而不是List吗？

<complexType name="BookShelf">
   <sequence>
      <choice minOccurs="0" maxOccurs="unbounded">
         <element name="newBook" type="string"/>
         <element name="oldBook" type="string"/>
      </choice>
   </sequence>
</complexType>
<complexType name="BookShelf">
   <sequence>
