I have always used the following as mytemplate per say :
<!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">
<head>
<title>title</title>
<meta name="keywords" content="keys" />
<meta name="description" content="desc" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Content-Language" content="en-us" />
</head>
----
Is it necessary or recommended to change to <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">?
The pages are all in english language and I do not want to limit it... in other words I would like the entire world to be able to view the pages.
Second question related to this is one .co.uk site I have which is also written in english of course, but I would like to limit it to the UK only... it seems that eventhough it is a .co.uk it does not appear to show in uk engines.
