Setting up a "basic framework" for my website projects, I'm wondering which meta elements are really necessary/recommended? In particular, I'd like to know how to deal with the language attribute(s)!? In the following example, I think sth. is repeated unnecessarily...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" dir="ltr">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta http-equiv="content-style-type" content="text/css" />
<meta http-equiv="content-script-type" content="text/javascript" />
<meta http-equiv="content-language" content="en" />
<meta http-equiv="language" content="en" />
<title> Title </title>
<base href="http://www.mydomain.com" />
<meta name="charset" content="utf-8" />
<meta name="content-language" content="en" />
<meta name="language" content="en" />
<meta name="description" content="description" />
<meta name="keywords" content="keywords" />
</head>
P.S. "content-language" = "language"?
