ISO-MAG (3+d)D and ISO(3+d)D are two faces of the same web page. In some cases, the two settings (and transformations) will be different.

@brantonc the dictionary says that _space_group_magn_ssg_transforms.source should have value ISO-MAG (3+d)D but the example uses ISOMAG-ISO(3+d)D. Either we should add an alternative value to the list of acceptable values for source, or there is a mistake in the example.

After thinking carefully about this, I feel that we should leave “ISO(3+d)D-MAG” as the only option. The example can be changed accordingly. Best wishes, Branton
