[NOTE]
====
Choosing the right attributes to set is the hardest thing in this process, because they carry the semantics of the variant.
Therefore, before adding _new attributes_, you should always ask yourself if there isn't an attribute which carries the semantics you need.
If there isn't, then you may add a new attribute.
