求教：xml schema定义子元素
xml文件如下：
<relationship type="relationship_Products" export="true">
<attribute type="type_Model" name="subObject"/>
<attribute type="false" name="checkFile"/>
<attribute type="true" name="exportSubObject"/>
<attribute type="String" name="attribute_FeatureAllocationType"/>
<attribute type="false" name="getTo"/>
<attribute type="true" name="getFrom"/>
</relationship>
attribute没有顺序要求，出现至少五次，name值为subObject，checkFile，exportSubObject，getTo，getFrom的必须出现一次，name值为attribute_$$$$$$$$的可以有零或多个，这个schema应该怎么定义呢？
thanks！

--------------------编程问答-------------------- 你的文档中type 和name是attribute的属性吗 --------------------编程问答--------------------
attribute是子元素的名称，都是一样的，所以我就不知道该怎么写了，type和name是每个attribute的属性
补充：Java , Java SE
