More Information

This method is abstract and should be explicitly defined in the child class, as needed. Also note that $output is passed by reference, so any changes made to the variable within the following methods are automatically handled (no return, echo, or print needed).

“Start Element”. Generally, this method is used to add the opening HTML tag for a single tree item (such as <li>, <span>, or <a>) to $output.
