I though adding the info to frmt_various.html was the most appropriate, but it is a bit intrusive. Should it be elsewhere, like the individual driver docs or in gdal_datamodel? I also though about adding an "s" key to the output of "--formats" format support string e.g. (rw+vs) I'll make the other changes you suggest. > > I'm not sure it is appropriate to backport in 1.9 however (new feature, output > of gdalinfo --format modified). 1.10 should be out soon hopefully.
