We discussed tags at the mid-cycle.  We decided against using them.
One reason is that tags are pretty new and are a moving target.
Another reason I was hesitant is that tags were designed to be user
facing.  As I recall, we didn't want the tags to affect code behavior.
But, maybe I misunderstood that.  We want service types to affect
IPAM, at least.

Brian Haley is going to put up a spec for this service type attribute
work.  Brian, would you mind posting a link to your spec review when
you've posted it?
