For any unknown trait name, the implementation will throw a DOMException 
with code NOT_SUPPORTED_ERR. Since there is no "+" trait, an exception 
will be thrown for your case. Differentiating between various types of 
non-existent traits incurs higher cost for implementations with no 
obvious gain.
