Kevin,

I *think* that the records will the x and/or y fields left NULL
should just result in features with no geometry.  I believe that
MapServer would just ignore these.  But I'm not absolutely sure of
this.

MapServer never uses the coordinate system offered by OGR (or any other
datasource) so you never need LayerSRS for MapServer's use.  If everything
in your map is in the same coordinate system you shouldn't need to declare
the projection at all.  If there is a mix of coordinate systems you would
need to declare them carefully with PROJECTION blocks.  I believe I'm just
confirming your existing understanding.

Best regards,
