问题描述
之类的标题说，我想，以确定是否数据是XHTML严格DOCTYPE标准属性。我似乎无法在网上找到的任何信息（看起来像它的HTML 5ish）。
Like the title says, I'm trying to determine if data is a standard attribute in the XHTML strict doctype. I can't seem to find any information online (looks like its HTML-5ish).
推荐答案
如果你在谈论与数据属性。如果你想在XHTML中使用它们，你需要XHTML5。
If you're talking about attributes with the data- prefix, that's indeed HTML5 only. If you want to use them in XHTML, you'd need XHTML5.
还有一个属性，它的名字就是数据。它是＆LT;对象＆gt; 元素就像在图像上的src 属性。这是两个严格和过渡的doctype HTML4和XHTML1的一部分。
There is also an attribute whose name is just data. It's for <object> elements and works like the src attribute on images. It's part of HTML4 and XHTML1 in both Strict and Transitional doctypes.
