Also, I should mention that now you can associate products with any existing taxonomy term
/products/product/vocabularies/taxonomy@id="X"/term = Term name
i.e.
<products>
<product>
<vocabularies>
<taxonomy id="6">
<term>Create Yourself</term>
</taxonomy>
<taxonomy id="5">
<term>Alexandre Herchcovitch</term>
</taxonomy>
</vocabularies>
...but you'll need a recent verion of importer form Bazaar
