		 1. Leave it, as it is native behaviour
		 2. Sets as empty string and removes the corresponding attribute when also has empty string
		*3. Sets as undefined and removes the corresponding attribute when "undefined" string discovered
		 4. Point 2. with checks for coincidence (e.g. use special string)
