Learning a bit about the differences between XHTML and HTML, I looked at the source of one of our pages:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

Is this correct? Seems like it’s trying to be a HTML page, but then has a link to an XHTML namespace?

    It looks like somebody was using an XHTML doctype, and the associated xmlns attribute:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

    And then they heard HTML5 was the shiny new doctype, so they changed to that and ended up with:

    <!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml" >

    Just to make it clear, this is what it should be:

    <!DOCTYPE html>
<html>
