[MAPSERVER-USERS] how mapserver handles different datum projections

Can anyone clarify how mapserver handles different datum in the map
projection and in the layers projection when serving a wms service?
Does MS apply datum transformations? If not, can it be done somehow without
converting the layers?
In my case I'm working with vector data, and have defined a map projection
using "init=epsg:code" syntax. Then at the layer level I use the same syntax
to declare the projection the data is in.
And finally I want my WMS service to be published in 3 different datum and
for that I advertise several epsg codes in the "wms_srs" metadata entry.
I'm noticing a shift in images produced by MS that indicate a datum shift is
not being applied. What can be done?
