次のような xsd があります (スニペット):
<xs:complexType name="IDType">
<xs:choice minOccurs="1" maxOccurs="2">
<xs:element name="FileID" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="IDNumber1" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="Number" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="PNumber" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="SS" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="Player" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="Prior" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="BIN" minOccurs="0" maxOccurs="1" type="an..35" />
<xs:element name="Mutual" minOccurs="0" maxOccurs="1" type="an..35" />
</xs:choice>
</xs:complexType>
<xs:simpleType name="an..35">
<xs:restriction base="an">
<xs:maxLength value="35" />
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="an">
<xs:restriction base="xs:string">
<xs:pattern value="[ !-~]*" />
</xs:restriction>
</xs:simpleType>
何らかの理由で、これは生成される Java コードです。

クラスがこのように生成され、単にある種の文字列配列ではないのはなぜですか? 何かを作成するたびに JAXBElements を作成する必要は本当にありませんか?
単に文字列などを表す型ごとにクラスを生成するにはどうすればよいですか?
