I've question concerning SRS: what should OGRWAsPLayer::GetSpatialRef()
for unknown SRS.
Context:
WAsP Map Editor has a couple of SRS that will be written in the first
line of the .map file. The first line looks like
+description | srs_name | map_editor version
Since there are very few SRS available, I use the 'description' field to
write the proj4 of the source SRS when I create a .map file (e.g. with
ogr2ogr -f WAsP dest.wasp source.shp).
I want to open .map files that where created by other means (e.g. WAsP
Map Editor). In this case the SRS will be unknown and it's fine since it
can be defined by other means e.g. with option -s_srs. But I don't wan't
the driver to do stupid things in this case.
