- protected function canAppendChild()
- final public function hasChildren() — Test if an element has no children.
- private function reduceChildren($children) — Reduce effectively-empty lists of children to be actually empty. This recursively removes `null`, `''`, and `array()` from the list of children so that @{method:hasChildren} can more effectively align with expectations.
