Howdy! I'm writing a theme from scratch finally. Some have ask me why I would do such a thing and I can only answer..."to be able to say I can". So having said that, the name space attributes in the html tag has me a bit confused. Why does WordPress include the code
<?php language_attributes(); ?> and not just a simple line of code like this.
<html xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
Doesn't that inclusion carry unnecessary weight and add a call slowing down the processes?
