When you sign a document with OpenOffice.org 3.2 or StarOffice 9.2 or a later version, and you open that document in an older version of the software, the signature will be displayed as &quot; invalid &quot; . Signatures created with older versions of the software will be marked with &quot; only parts of the documents are signed &quot; when loaded in the newer software.
如果使用 OpenOffice.org 3.2、StarSuite 9.2 或更新版本对某个文档进行签名，然后在该软件的较旧版本中打开此文档，则签名会显示为“无效”。如果使用该软件的较旧版本创建了签名，然后在较新版本中加载该签名，则签名会被标记为“仅对部分文档进行了签名”。
