I'm with you on the dictionary part that we don't need null there.

I'm talking about the corresponding attribute on the DataChannel object. 
The attribute from which you can read back, e.g., maxRetransmits when 
the object has been created. And the question was if you think it's ok 
for that *attribute* to be nullable.

I'll just go ahead and do the change and then we can look at the result 
and take it from there.
