* @param string $name The property name. Available properties are defined in the
* columns of the webpage_properties table and include:
* - active
* - locked
* - translation_memory_id
* - enable_live_translation
* - auto_approve
* @param SweteWebpage $root The root webpage from which to calculate.
* @param mixed $parentEffectiveProperty The effective property value of the $root's parent.
* @param mixed $inheritVal
