注释架构
本主题介绍 Microsoft Annotations Framework 用来保存和检索用户批注数据的 XML 架构定义 (XSD)。
Annotations Framework 将批注数据从内部表示形式序列化为 XML 格式。 Annotations Framework XSD 架构描述了用于此转换的 XML 格式。 该架构定义独立于实现、可用来在应用程序之间交换批注数据的 XML 格式。
Annotations Framework XML 架构定义由两个子架构组成
批注 XML 核心架构（核心架构）。
批注 XML 基本架构（核心架构）。
核心架构定义 Annotation 的主 XML 结构。 核心架构中定义的大多数 XML 元素对应于 System.Windows.Annotations 命名空间中的类型。 核心架构公开应用程序可在其中添加自己的 XML 数据的三个扩展点。 这些扩展点包括 Authors、ContentLocatorPart 和“内容”。 （内容元素以 XmlElement 列表的形式提供。）
本主题中描述的基本架构定义 Authors 和 ContentLocatorPart 的扩展，以及初始 Windows Presentation Foundation (WPF) 版本随附的内容类型。
