I think the setContent(XXX xxx) methods make alot of sense. I think it 
would be a mistake, and kind of annoying to have just setContent methods 
for a List and a String. If you want to take a minimalist approach to the 
question, then why have one specifically for just String? A String is just 
another object, so we might as well do it all with just the List method 
and add the String to the List then add the List.

In my opinion, the many setContent methods would make the API much easier 
to use. If I want to add an Element, I don't need to know that I have to 
add it to a List and then setContent, I can just setContent. The same 
would go for String and everything else, all with one polymorphic method. 
Very convenient if you ask me. I think that this change would facilitate 
removal of some other methods (been a while since I have looked at the 
API) and thus make the API less cluttered. I could be wrong, just my 1.5 
cents.
