Don't you think Taxonomie's are just another way to implement
The same would be possible if you create nested containers for example and allow to choose multiple containers?
So what's the correct purpose/best practice for correct use of containers/taxonomy?
Are the containers just for lists for example products,
and then you would create for example sections in taxonomy (USA, Asia, Europe) and relate the products.
Or create a list and add to the list the containers USA, Asia, Europe and add the products correctly to the sections.
I hope my english is readable ;)
