Would it be useful, and is it possible to define the refElements

Looks like this already got answered, but yes, sequence<Node> should
make that work.
OK. Then I'm not sure what the practical difference between the
Element[] or sequence<Element> would be then, nor which one to use.
I'm not either. That's why Cameron is cced.
If using webidl array/sequence types, that would help with the
iteration, but not the large allocation.
OK, does that mean it's not really worth defining like that?
I think this is an edge case we shouldn't worry about.
Perhaps famous last words.....
Yes, I just checked and I think you may be right. The WebIDL algorithm
to convert an ECMAScript array to an IDL value of type T[] iterates the
array and says:
While i < n:
Let x be the result of calling [[Get]] on V with property name ToString(i).
Set Ei to be the result of converting x to an IDL value of type T.
This step can throw (as part of the conversion process defined for
converting to type T); seems like that would involve throwing from the
whole algorithm.
