What events within the DOM does Mutation Observers not account for? (If any)

  boolean childList = false;
  boolean attributes;
  boolean characterData;
  boolean subtree = false;
  boolean attributeOldValue;
  boolean characterDataOldValue;
  sequence<DOMString> attributeFilter;

I know MuObs account for the above things to look for but there anything that MuObs don't account for? w3 mozilla
