Ali Lown resolved WAVE-17.
--------------------------

    Resolution: Won't Fix

The server is responsible for ensuring this is never a problem, as it already 
knows all the document ids in use when generating a new one.

>                 Key: WAVE-17
>                 URL: https://issues.apache.org/jira/browse/WAVE-17
>             Project: Wave
>          Issue Type: Bug
>            Priority: Minor
>
> Currently, document-ids do not include enough information to guarantee them 
> to be unique.  This could (not likely, but could) result in collisions when 
> document creating operations are submitted to the authoritative Federation 
> Host from multiple sources.
> Suggested solutions so far are:
> 1) Include the domain of the submitting host in the document-id.  This 
> guarantees no collisions.
> 2) Require document-ids to be at least a certain length, to make collisions 
> much less likely.
