java - http://schemas.opengis.net/wfs/1.1.0/wfs.xsd の JAXB クラスの生成

Question

このスキーマのクラスを生成するために JAXB を使用しようとしています: http://schemas.opengis.net/wfs/1.1.0/wfs.xsd

そのスキーマをローカルファイルにダウンロードして、JAXB クラスを生成しようとしています。まず、次のエラーが表示されます。

[ERROR] Property "Title" is already defined. Use &lt;jaxb:property> to resolve this conflict.
  line 261 of http://www.w3.org/1999/xlink.xsd

グーグルで調べたところ、バインディングファイルを使用する必要があることがわかりました。

<jxb:bindings version="2.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
    xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <jxb:bindings schemaLocation="http://www.w3.org/1999/xlink.xsd"
        node="/xs:schema">

        <jxb:bindings node="//xs:attributeGroup[@name='locatorAttrs']">
            <jxb:bindings node=".//xs:attribute[@ref='xlink:title']">
                <jxb:property name="title1" />
            </jxb:bindings>
        </jxb:bindings>

        <jxb:bindings node="//xs:attributeGroup[@name='arcAttrs']">
            <jxb:bindings node=".//xs:attribute[@ref='xlink:title']">
                <jxb:property name="title2" />
            </jxb:bindings>
        </jxb:bindings>

    </jxb:bindings>

    <jxb:bindings
        schemaLocation="http://schemas.opengis.net/gml/3.1.1/base/geometryPrimitives.xsd"
        node="/xs:schema">
        <jxb:bindings node="//xs:element[@name='_Solid']">
            <jxb:factoryMethod name="gmlAbstractSolidElementFactory" />
        </jxb:bindings>
    </jxb:bindings>

</jxb:bindings>

しかし、そのバインディングファイルを使用すると、他にも大量のエラーが発生します。

Failed to produce code.

これは、他の人が JAXB クラスを生成したであろうスキーマのように見えるため、少し驚いていますが、Google は何も表示しないようです。以前に JAXB を使用したことがありますが、これは以前に見たものより複雑なようです。

このスキーマに使用する必要がある特定のバインディングファイル、または特定の JAXB 設定はありますか?

免責事項:私は、WFS 1.1.0を含むほぼすべての OGC スキーマをコンパイルするogc-schemasプロジェクトの主任開発者です。

OGC スキーマは、コンパイルが非常に困難です。多くのバインディング、カスタマイズ、および場合によってはパッチが必要です。したがって、 ogc-schemasプロジェクトによって提供されるコンパイル済みの schmeas を使用することをお勧めします。コンパイルされた WFS 1.1.0 スキーマのこのアーティファクトを取得します。

WFS 1.1.0 の場合、いくつかのバインディングが必要になります。

それとは別に、スキーマの相対的な場所の URL をグローバルに修正するなど、いくつかのマイナーパッチをスキーマに適用する必要がありました。

ogc.パッチ

しかし、実際には、既にコンパイルされたスキーマを使用するだけです。これがこのプロジェクトの目的です。
