Yes - the number of decimal places given.
The question seems a little fuzzy. I assume Michael meant "accuracy"
of the coordinates, so much as the radius of interest of the specified
coordinates? A center of a city may be fairly accurate, with the
bounds of the city specified as a radius.
Limiting this radius definition as just a limit of number of decimal
places doesn't work.
GeoRSS uses a "radius" element, which could be a uf class and would
specify in meters, kilometers, or miles (itself a discussion for
units). Or perhaps better would be a featuretypetag (again using
GeoRSS as a working case example) that can specify "city":
The crater is <span class="geo"><span class="radius">50 meters</span>
centered at <span class="latitude">37.386013</span>, <span
class="longitude">-122.082932</span></span>.
The eclipse can be seen from <div class="geo">
<abbr class="latitude" title="37.408183">N 37° 24.491</abbr>
<abbr class="longitude" title="-122.13855">W 122° 08.313</abbr>, or
anywhere in the <span class="featuretypetag">city</span>
</div>.
