Represents a tagged XML element. Elements are characterized by having children, attributes, and names, and can themselves be children.
Create a new element.

if node.kind_of? String
node = [ :text, node ]

end
Append a child to this element, optionally under a provided namespace. The namespace argument is ignored if the element argument is an Element object. Otherwise, the element argument is a string, the namespace (if provided) is the namespace the element is created in.
