That is the XML namespace of the tag. Imagine, for a moment, that you
had a document that was XHTML but included some XML measurement data
for a person. That measurement data may have a <head> element for the
size of the person's head. In order to keep the XHTML <head> separate
from the measurement <head>, you would need to differentiate via
namespaces.
Under certain circumstances, I think that ElementTree does not require
you to list the namespace. These documents have two namespaces (the
XHTML one and the Kid one), so that may be why ElementTree sticks the
namespace in front of the tag name.
