<area id="1234">
    <tag k="landuse" v="industrial" />
    <outer>
        <nd ref="1"/>
        <nd ref="2"/>
        <nd ref="3"/>
    </outer>
    <inner>
        <nd ref="4"/>
        <nd ref="5"/>
        <nd ref="6"/>
    </inner>
    <inner>
        <nd ref="7"/>
        <nd ref="8"/>
        <nd ref="9"/>
    </inner>
