In the send(data) algorithm, step 3, says:
data is not a DOMString or Document
The stringification mechanisms of the host language must be used on
data and the result must be treated as if data is a DOMString.
I'm not sure what that means. For instance, if data is an Element, would
it be serialized with .outerHTML or similar? Could it be clarified, or
could an example be added, or, if the spec is fine and it's just me being
slow, be explained to me? :-)
