Think about this a little and I think you'll see why this restriction makes
some sense. Say we allowed a string here. Introspection would create one and
then try and configure that string (using set methods) - but strings are
immutable and once created can't be configured.
So, if we want to support Strings in this way, we would need to treat them
specially (not like other objects) and use the element's text as the
string's value upon construction.

I think you actually want to have an addText method for that. The
constructor approach is more for attribute style setXXX methods.
