Neil,

The above is fine, but by default MapServer will assume your
input layer is the same projection and do nothing with it.
You need to add the following declaration for the LAYER:

  PROJECTION
    "+proj=latlong +datum=WGS84"
  END

MapServer does not normally pull the layer coordinate
system from the datasource.

Best regards,
