Description Daniel Cheng 2013-03-13 15:16:56 PDT 
The spec does not define DataTransfer.types as a nullable type:
15:06 < dcheng> Question... if the spec defines an attribute to return a DOMString[], it would be 
                incorrect to return null if it's empty right?
15:07 < annevk> dcheng: yes

So we shouldn't ever be returning null.

Mozilla's implementation of DataTransfer confirms this: http://mxr.mozilla.org/mozilla-central/source/content/events/src/nsDOMDataTransfer.cpp#265 always returns a non-null list (unless the allocator failed).
