Re: [alto] New Incremental Update draft

Wendy, Richard,

great work.

One question that came up while reading:

1. Is it allowed to use "start-updates" and "stop-updates" in one HTTP 
request? I found nothing specific that neither supports nor contradicts 
that.
     Intuitively, I would say no, it is not allowed to have both in one 
request but I am not entirely convinced.
