Hmm, I don't know... As with most of our request/responses for LS - we 
haven't defined what is required and what is not.

I wrote the page you mentioned basing on real requests and responses and 
examples made by Jason and Martin, so they may not be strict.

I'll look into the code and see how it actually works. Maybe there would 
be a reason for distinguishing such variants of data+datum and data 
without datum for client applications
