关于XHTML 1.1 的 DOCTYPE，总出现警告！

fen · Nov 1, 2007

我的写的是
HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
这是警告信息

DOCTYPE Override in effect!

The detected DOCTYPE Declaration "<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">" has been suppressed and the DOCTYPE for "XHTML 1.1" inserted instead, but even if no errors are shown below the document will not be Valid until you update it to reflect this new DOCTYPE.

还有
HTML:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="zh-cn" lang="zh-cn">
也无法通过 1.1的检测，出现错误信息

Line 4, Column 65: there is no attribute "lang".

…http://www.w3.org/1999/xhtml" xml:lang="zh-cn" lang="zh-cn">

You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.

How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute. If you received this error when using the <embed> element to incorporate flash media in a Web page, see the FAQ item on valid flash.

XHTML 1.1 ，太超前了。

還是改爲 XHTML1 相關的吧。

第二個既然說了沒有 lang 屬性，去掉不就可以了？

不過下面的代碼卻不會出現你遇到的第一個警告。

HTML:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="zh-cn">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>

<body>
<p>My Body</p>
</body>
</html>

我把你的这句话复制了一遍居然就通过了……
