In fact, the position of all objects changes slightly over time and
a coordinate should be a vector indicating a position and a
(presently best value of) direction and speed of drift.<br>
The Greenwich meridian is presently 102m west away of the zero
latitude of a GPS and it continues to drift.<br>
See <a moz-do-not-send="true"

Meridian</a> which is now <span class="longitude">0.0014864° W
by its nodes (which should have the same value BTW).</span><br>

All the best,

<div>Example:<br>
I know a park that has a few dozen benches. They are there
practically all-year-round, but their position changes every
now and then. A fixme would imply that the problem can be
fixed (which does not seem practical), leaving them out
completely is less than ideal and leaving them as nodes gives
a false sense of precision, which is not perfect either. Is
there a way of saying "there are benches somewhere around
here"?</div>
