If the server "returns time-stamps that can only cover one document per 
time-stamp", then the client MUST only send a single input document, SHOULD 
isn't right for that case, since SHOULD means "there may exist valid 
reasons in particular circumstances to ignore a particular item":
http://www.faqs.org/rfcs/rfc2119.html

The above text also doesn't say what do if the client doesn't know what 
type of time-stamp the server returns.  The below text covers that case: 
the client should play it safe, and send a single document.

So I still like the below text better.  What are your objections to the 
below text? (do you think it's ambiguous?  or do you think it's behavior is 
wrong?).
