I did not mean versioning of the schema, but versioning of the
(topology) instance.

E.g.

F: "Hey guy's, this is my latest network!"

<nml:topo id="freekishnet" version="2012-03-12">
   <!-- awesome stuff -->
</nml:topo>

(... After a well deserved night's sleep ...)

F: "Hey guys, I added a unloaded swallow to my network today, totally
putting yesterday's network in shame!"

<nml:topo id="freekishnet" version="2012-03-13">
  <!-- even more awesome stuff -->
</nml:topo>

It has the same identifier, but because it has a different version, you
know which one is the latest-and-greatest.
