Namespaces.
Unlike in X(HT)ML, namespaces in HTML5 are not denoted by a prefix. Rather,
anything inside an <svg> tag is in the SVG namespace, anything inside the
<math> tag is in the MathML namespace, and anything else is inside the HTML
namespace. No other namespaces are supported, so this can be an enum only.
