Project 元素 XML 架构
下面显示了定义 Project 元素的 Microsoft Office Project 2007 XML 数据交换架构 (mspdi_pj12.xsd) 部分。
OutlineCodes、WBSMasks、ExtendedAttributes、Calendars、Tasks、Resources 和 Assignments 元素都在 Project 元素中定义;但是，此架构参考中的单独主题中显示了其中每个元素的详细架构信息。
Project 2007 SDK 下载中包含完整的 Project XML 数据交换架构。 有关 Project 2007 SDK 下载的链接，请参阅 欢迎使用 Microsoft Office Project 2007 SDK。
