HTML5 <html> attributes xmlns, lang, xml:lang -


i don't understand html5 specifications lang , xml:lang attributes of opening <html> tag. scrolling bit, understand xmlns "talisman" (has no effect), lang , xml:lang? should used? if so, should set to?

everything i've seen , heard suggests should stick to

<!doctype html> <html>   <head>     <meta charset='utf-8'>

(or whatever character set want). if want language associated page can use "lang" attribute on <html> tag.

since html5 not xml, really, find weird use xml: namespace stuff.
