{@section Immutability and thread safety}This class is immutable and thus thread-safe if the property
values (not necessarily the map itself) and the {@link CoordinateSystemAxis} instances given to the constructor are also immutable. Unless otherwisenoted in the javadoc, this condition holds if all components were created using only SIS factories and static constants.
