       "element_nodes($node)"
           Returns a list of the element children of $node.

       "text_in_node($node)"
           Returns the string combining the text nodes within $node.

       "isTeXtNode($node)"
           Checks whether $node is a text node.

       "isElementNode($node)"
           Checks whether $node is a element node.

       "isChild($child,$parent)"
           Checks whether $child is a child of $parent.

       "isDecscendant($child,$parent)"
           Checks whether $child is a descendant of $parent.

       "isDecscendantOrSelf($child,$parent)"
           Checks whether $child is a descendant of, or the same as, $parent.

       "new_node($nsURI,$tag,$children,%attributes)"
           Creates a new element node with tag $tag (in the namespace $nsURI), with the children
           in the array ref $children (if any) and assigning the given attributes.

       "append_nodes($node,@children)"
           Appends the given children to $node.

       "clear_node($node)"
           Removes all element and text children from $node.

       "maybe_clone($node)"
           Clones $node if it has a parent, otherwise returns it.

       "copy_attributes($to,$from)"
           Copy all attributes from $from to $to.

       "rename_attribute($node,$from,$to)"
           Rename the attribute $from to $to on the node $node.

       "remove_attr($node,@attr)"
           Remove the given attributes from $node.

       "get_attr($node,@attr)"
           Returns the list of values for the given attributes on $node

       "set_RDFa_prefixes($document,$map)"
           This method scans the document's RDFa attributes, extracting the prefixes used.  These
           prefixes are then filtered through a $map of known RDFa prefixes and the ones allowed
           are declared globally for the document via the "prefix" attribute of its root element.
