SRS - layer with two valid EPSGcodes

[Stefanie Weykam]

Yes, but this does not avoid reprojection of the layer if the client chooses
the other ellipsoid, does it? As an arctefact the grid lines would be
shifted several hundred meters in both directions.

So, what is the best way to handle this -perhaps unusual- situation?
- offering only one of these EPSG codes in order to force the client to use
the first datum?
- duplicate the layer and offer each in a different projection?? (I do not
really favour this one)
- any other suggestion??

AFAIK you just advertize using wms_srs METADATA (space delimited list).

I have a polygon layer, a mesh witch fits to exact coordinates on the UTM
grid.
If the datum is changed, the mesh should still fit to the original
coordinates and should not be reprojected.

I guess, I could work around this in our own application, but how do I
advertise this layer with several valid EPSG codes to clients?
