Hi Liv,

I apologise if this question has been raised before in this debate.

In DanZIG, we're also not using the attribute set architecture 
specifically. However, we did choose to create a new attribute set (Dan-1) 
for attributes of specific national relevance, rather than moving 
everything into Bib-1. This was based on the observation that pretty much 
all targets on the Danish market were capable of supporting multiple 
attribute sets when pushed.

Can you say something about your thoughts in this regard?
