I just have to say that this is far best data import plugin!
I still need one thing to modify to make it perfect :)
There are 2 solutions, and I would actually need some advice which one would be easier to achieve...
1. To import data directly to "custom taxonomies" from datafiels of xml, just like it can already do the same thing with "custom fields"
2. To try to find a plugin that will copy data from custom fields to custom taxonomies on a daily basis "cron".
I would appreciate any help
