新生的 XInclude

前几天看Don Box 的Blog，有篇叫All I want for Christmas is an XInclude 1.0 Full Rec 的帖子。首次看到了XInclude，也没有仔细看。

今天，我看W3C，才看到这个文档——XML Inclusions (XInclude) Version 1.0
他的介绍是这样的：

Many programming languages provide an inclusion mechanism to facilitate modularity. Markup languages also often have need of such a mechanism. This specification introduces a generic mechanism for merging XML documents (as represented by their information sets) for use by applications that need such a facility. The syntax leverages existing XML constructs - elements, attributes, and URI references.

大概是说：
很多程序设计语言提供一种包含机制，以便增强语言的模块性。标记语言通常也需要这样的一种机制。这个规范提供了一种通用的机制来实现XML文档的归并以方便应用程序使用。
