如何在Java中为使用XMLBeans生成的XML文件设置schemaLocation？

我使用Java中的XMLBeans生成了一个XML文件。结果是这样的：

<ipdr:IPDRDoc IPDRRecorderInfo="192.168.95.82" xmlns:ipdr="uri://www.ipdr.org/namespaces/ipdr" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:DOCSIS-QOS="uri://www.cablelabs.com/namespaces/DOCSIS/3.0/xsd/ipdr/DOCSIS-QOS">

    <ipdr:IPDR xsi:type="doc:SAMIS-TYPE-1" xmlns:doc="uri://www.cablelabs.com/namespaces/DOCSIS/3.0/xsd/ipdr/DOCSIS-SAMIS-TYPE-1">   
    <DOCSIS-QOS:ServiceTimeCreated>1474597117000</DOCSIS-QOS:ServiceTimeCreated>
    <DOCSIS-QOS:ServiceTimeActive>100</DOCSIS-QOS:ServiceTimeActive>
    </ipdr:IPDR>  

</ipdr:IPDRDoc>

我怎么做？我尝试使用

xmlOption.setSaveSuggestedPrefixes（suggestedPrefixes）但没有成功。
有办法吗

<ipdr:IPDRDoc IPDRRecorderInfo="192.168.95.82" xmlns:ipdr="uri://www.ipdr.org/namespaces/ipdr" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:DOCSIS-QOS="uri://www.cablelabs.com/namespaces/DOCSIS/3.0/xsd/ipdr/DOCSIS-QOS" xsi:schemaLocation="uri://www.cablelabs.com/namespaces/DOCSIS/3.0/xsd/ipdr/DOCSIS-SAMIS-TYPE-1
                    DOCSIS-SAMIS-TYPE-1_3.5.1-A.1.xsd">

    <ipdr:IPDR xsi:type="doc:SAMIS-TYPE-1">   
    <DOCSIS-QOS:ServiceTimeCreated>1474597117000</DOCSIS-QOS:ServiceTimeCreated>
    <DOCSIS-QOS:ServiceTimeActive>100</DOCSIS-QOS:ServiceTimeActive>
    </ipdr:IPDR>  

</ipdr:IPDRDoc>
