Usually you can simply use the DefaultSRS and tell OGR to re-project the result
into something else with -t_srs parameter. Sometimes it can still be better to
use the OtherSRS from the server. For example, because of deformations OGR gives
1-2 meter local conversion errors when doing transformations between EPSG:2393
and EPSG:3067. The WFS server may do the conversion with some more accurate
method and then it would be better to use &SRSNAME= in the ORG connection.
