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? --Sebastian At 09:55 20-03-2003 +0100, Liv Aasa Holm wrote: >We (NORZIG) are definitely on the list and we have worked in this area for >more than 20 years now (network protocol area).
