避免使用js的敏感词汇（如key="key"）

错误示范

<property key="key" type="attribute" required="false" dataSource="nodes">
  <caption>Id</caption>
  <description></description>
  <attributeTypes>
    <attributeType name="String" />
  </attributeTypes>
</property>

正确示范

<property key="_key" type="attribute" required="false" dataSource="nodes">
  <caption>Id</caption>
  <description></description>
  <attributeTypes>
    <attributeType name="String" />
  </attributeTypes>
</property>
