docs: Adds a set of element actions to be performed in this mode
  for elements in a specified namespace.
  
  @param ns The namespace pattern.
  @param wildcard The wildcard character.
  @param actions The set of element actions.
  @return true if successfully added, that is the namespace was
  not already present in the elementMap, otherwise false, the
  caller should signal a script error in this case.
