Would it be useful to be able to add annotations to base layers to indicate
where they are wrong. For example to add a polygon to a Bing or Yahoo aerial
or OS Streetview layer that partly obsures the image and says 'this area has
changed' or something similar. This would need to be flagged for re-checking
when the source material is updated.

Another approach would be for the submit process to put up an alert 'you are
adding a feature which has previously been deleted - the deletion included
the following comment in the changeset'.
