未声明的命名空间与邻：allowincell在docx4j Differencer.diff（）调用

当一个文档转换过程的结果比较原始与docx4j，我们得到以下错误为我们的测试情况之一：未声明的命名空间与邻：allowincell在docx4j Differencer.diff（）调用

com.topologi.diffx.xml.UndeclaredNamespaceException: The namespace URI "urn:schemas-microsoft-com:office:office for allowincell" has not been mapped to any prefix.

我消除利用该方法在原始文档进行比较，以本身被改造的探讨过程中引入的误差（基于this answer）的可能性：

private static final String compareToSelf(File fileToCompare) throws Docx4JException { 
    WordprocessingMLPackage olderPackage = WordprocessingMLPackage.load(fileToCompare); 
    WordprocessingMLPackage newerPackage = WordprocessingMLPackage.load(fileToCompare); 

    Body newerBody = newerPackage.getMainDocumentPart().getJaxbElement().getBody(); 
    Body olderBody = olderPackage.getMainDocumentPart().getJaxbElement().getBody(); 

    java.io.StringWriter sw = new java.io.StringWriter(); 
    javax.xml.transform.stream.StreamResult result = new javax.xml.transform.stream.StreamResult(sw); 
    Calendar changeDate = null; 

    Differencer pd = new Differencer(); 
    pd.setRelsDiffIdentifier("blagh"); // not necessary in this case 
    pd.diff(newerBody, olderBody, result, "someone", changeDate, 
       newerPackage.getMainDocumentPart().getRelationshipsPart(), 
       olderPackage.getMainDocumentPart().getRelationshipsPart()); 

    return sw.toString(); 
}

的Stac ķ跟踪：

我解压* .docx文件和o:allowincell似乎是在包含document.xml的<w:document>标签与xmlns:o="urn:schemas-microsoft-com:office:office"正确映射。

测试文件可以从这里才可下载：https://docs.google.com/open?id=0B6_h2TfqvEdeZE43X3RSWnFIZHc

就如何解决这个问题的任何想法？

此警告在执行过程中也会出现，不确定它是否相关：WARN [org.docx4j.openpackaging.contenttype.ContentTypeManager] - ' – 2012-08-13 14:02:20

在Docx4jDriver在管线192和206有：

e.setAttributeNS("http://www.w3.org/2000/xmlns/", "xmlns:w", 
      "http://schemas.openxmlformats.org/wordprocessingml/2006/main");

你可能需要添加的xmlns：○。最终，需要对代码进行改进以自动添加所有相关的名称空间。
