使用ibatis时遇到Error parsing XPath '/sqlMapConfig/sqlMap'低级错误

使用ibatis时，遇到一错误。是疏忽造成的，留作记录。
错误信息如下：

 代码如下：

<insert id="Insert" parameterClass="uecpSplitOrder">
		insert into umpay.$tableName$(
			<include refid="Insert_column" />
		) 
		values (
			<include refid="Insert_value" />
		)
</insert>
<sql id="Insert_column">
................................
</sql>
<sql id="Insert_value">
.................................
</sql>

 相信睿智的各位都已经发现了问题。没错，引用者放在了被引用者的前面，ibatis解析的时候找不到refid的对象，从而导致出错。
