Remarks
Instead of this constructor, you can use the overloaded variant without the info parameter, because the info is usually extracted automatically from the authority and authorityCode. The extracted info can then be examined, for example in the dump file from a SpyOperator.
But the automatic extraction can fail (giving an info with only default properties), for example if your datum shift comes from an EPSG version newer than what Carmenta Engine supports, or from some other source.
