Spain and european countries requirements

Tax module is poor for european countries.

Taxes require a name for a correct invoice. We can add 16% of IVA (VAT in europe) for a service provided and later we substract a 15% of IRPF when the seller is a professional and not a company.

By other hand in Spain there are 52 provinces. Ceuta, Melilla and Canary Islands are exent for IVA taxes. I need to stablish a general rule for country "Spain" but with exceptions for those provinces. Maybe the rules should be evaluated in order and stop when one of then was true.

For diferent product types we have diferent taxes, a 16%, a 7% or a 4%. I suppose it should be solved creating diferent products types so that's not a feature request for these module.

The same problem occurs on other European Union countries and I suppose the same is for other countries. I wish these module was upgraded for more international requirements.

Best regards
