As a side note, I'm probably stating the obvious here, but this is only a problem because your type is `*Attribute`. Should it be `Attribute` instead, your struct would be properly initialized with its fields to their zero value.
I mention it because I'm not sure myself why, from a design point of view, it's such a common practice to make pointers out of everything by default (I like the idea that what I pass as parameter can only be altered if I explicitly allow it).
