I'm using xhtml1-strict.dtd and I just realized I have an error in my HTML tag and I'm not sure how to fix it.
<?xml version="1.0"?>
<!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">
Error:
----:[1]^Warning: <html> has XML attribute "xml:lang".
How can I fix that?
