Here is a list of the minimized attributes in HTML and how they should be written in XHTML:
这是在HTML中简写的属性和其在XHTML中应该怎样书写的列表：
| HTML | XHTML |
|---|---|
| compact | compact="compact" |
| checked | checked="checked" |
| declare | declare="declare" |
| readonly | readonly="readonly" |
| disabled | disabled="disabled" |
| selected | selected="selected" |
| defer | defer="defer" |
| ismap | ismap="ismap" |
| nohref | nohref="/nohref" |
| noshade | noshade="noshade" |
| nowrap | nowrap="nowrap" |
| multiple | multiple="multiple" |
| noresize | noresize="noresize" |
HTML 4.01 defines a name attribute for the elements a, applet, , i, img, and map. In XHTML the name attribute is deprecated. Use id instead.
对于a, applet, , i, img和map，HTML 4.01中定义了一个name属性，在XHTML中是不赞成这样做的，使用id来代替。
This is wrong:
这是错误的：
<img src="picture.gif" name="picture1" />
This is correct:
这是正确的：
<img src="picture.gif" id="picture1" />
Note: To interoperate with older browsers for a while, you should use both name and id, with identical attribute s, like this:
注意：为了版本比较低的浏览器，你应该同时使用name和id属性，并使它们两个的值相同的，像这样：
<img src="picture.gif" id="picture1" name="picture1" />
IMPORTANT Compatibility Note:
兼容性注意点：
To make your XHTML compatible with today''s browsers, you should add an extra space before the "/" symbol.
让你的XHTML兼容当前的浏览器你应该在/标记前添加空格
The lang attribute applies to almost every XHTML element. It specifies the language of the content within an element.
lang属性可以应用于几乎所有的XHTML元素。它指定了元素中内容的语言
If you use the lang attribute in an element, you must add the xml:lang attribute, like this:
如果你像在一个元素中应用lang属性，你必须加上xml:lang属性，像这样：
<div lang="no" xml:lang="no">Heia Norge!</div>
All XHTML documents must have a DOCTYPE declaration. The html, head and body elements must be present, and the title must be present inside the head element.
所有的XHTML文档都必须有一个DOCTYPE声名。html、head和body元素必须出现，并且title必须在head元素里
This is a minimum XHTML document template:
这是一个极小的XHTML文档模板
<!DOCTYPE Doctype goes here> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Title goes here</title> </head>
<body> Body text goes here </body>
</html>
Note: The DOCTYPE declaration is not a part of the XHTML document itself. It is not an XHTML element, and it should not have a closing tag.
注意：DOCTYPE声明并不是XHTML文档自身的一部分。它也不是XHTML元素，它不该有关闭标签。
Note: The xmlns attribute inside the <html> tag is required in XHTML. However, the validator on w3.org does not complain when this attribute is missing in an XHTML This is because "xmlns=http://www.w3.org/1999/xhtml" is a fixed and will be added to the <html> tag even if you do not include it.
注意：XHTML文档要求xmlns属性出现在html标签中。然而，w3.org的校验器不会由于这个属性没有出现在你的XHTML文档中而报告错误。这是因为"xmlns=http://www.w3.org/1999/xhtml"是一个固定的值，即使你的文档里没有包含它，它也会自动加上的。
