XHTML中的自定义属性是否正确 [英] Are Custom Attributes OK in XHTML

问题描述

我了解，根据HTML规范，向元素添加自定义属性是无效的。

I understand that according to the HTML specification, it's invalid to add custom attributes to elements. Is this also invalid with XHTML?

我认为XHTML是XML家族的一部分，因此是可扩展的。可扩展性是不是可以使用自定义属性？

I thought XHTML was part of the XML family, and as such was extensible. Being extensible, isn't it ok to use custom attributes?

推荐答案

自定义属性不会被标准的W3C验证器视为有效。
不过，您可以定义自己的文档类型定义（DTD）。有关更多信息，请参见 http://www.alistapart.com/articles/customdtd/

custom attributes won't be considered valid by the standard W3C validators. You can define your own document type definition (DTD) though. See http://www.alistapart.com/articles/customdtd/ for more information about that.
