This is an excellent description of more or less what I was trying to
say (but didn't so well), and I think it would be a good addition to
formal tagging guidelines.

Yes, it effectively answers my question.  For a private road I'll use
highway=residential if the road is named and recognized by our county
property appraiser, and I'll use highway=service otherwise.
Additionally, I'll sprinkle access=private as appropriate.

I don't understand what was meant by These are also role=access in
the relation.  What relation?

People are incorrectly marking ways with noname=yes just because there 
are no signs. This doesn't mean that it doesn't have a name.

A relation of type=site probably.

Indeed, most round abouts have names, even if they are unmarked. Most
can be found due to local knowledge, or maybe the name of the largest
round, or pub at the roundabout.

I'm not suggesting you guess of make it up, But if its known as the
Sans Pareil Roundabout because the pub next to it has been there
longer than the round about its self, then name it. Most of the names
are used by Routing software to discribe routes rather than for
addressing, so you have some logical reason, then add it. If it does
have a different name, that later becomes clear it will get changed,
or maybe the council will name it. However I'm not suggesting tagging
for the renders or the routing software, Its more local knowledge
which is one big gain of OSM.

Be aware however that loads of towns are getting the round abouts
sponsored for advertising. So if its labled with loads of adverts
don't go and label it the with the adverts, They have this amazing
habit of changing.

http://wiki.openstreetmap.org/wiki/Relations/Proposed/Site

   It would be good to update the Wiki for common and logical roles for this 
relation:

 access / entrance
 perimeter

   I didn't know whether to just add them to the Wiki because it's still in 
proposal stage, or if it was a good idea.

  Thanks,

You should better say In my country, most... because it's not
generaly the case in mine.

Note that only Cloudmade's lint and JOSM validator seem to complain
about unnamed roundabouts, not KeepRight, thanks to Harald who kindly
replied to my request. I'm always supporting default rules and values
but not if they are too different from country to country. E.g. saying
highway=motorway implies bicycle=no; foot=no is fine. But not that
junction=roundabout implies a tag name. It seems to be true in some
countries but then the tools have to fix this rule for those countries
only, not globaly.

 The elements which are within the perimeter can be calculated from the
 perimeter itself.  

We tend to explicitly tag whether something belongs to the site or not. 
You might, for example, have a bridge spanning the site or other kinds 
of transit routes that are not part of the site, but serve to travel 
through/across the site without entering it. A rule like the one you 
suggested would make that impossible.

 It's redundant to have the same information
 expressed twice, and doing so will only lead to conflicting data.

The relation would express whether something is logically part of the 
site; the geometry would express whether something covers the same 
ground as the site. This is not the same information.

That doesn't make it right.

How not?  A bridge which goes over a site would be in a different
layer, and wouldn't cover the same ground.  A road which goes
through the site, but is not considered part of the site, would split
the site into two parts, and would make the perimeter a multipolygon.

Note that all I said is If you can outline a perimeter, you don't
need a relation.  If you can't outline a perimeter, then you may need
a relation.  Having a perimeter and a relation is the problem.
