<description lang='eng'>Comments may appear anywhere in a document outside other markup. An XML processor may, but need not, make it possible for an application to retrieve the text of comments. The string "--" (double-hyphen) must not occur within comments. </description>
<description lang='chi'>注释可以出现在文档的任何地方, 但必须位于其它标记之外. 一个XML处理器或许应该(但并非必须)能够让应用程序有办法得到注释的内容. 此外, 双连字符 "--" 不应该出现在注释里. </description>
