[trunk] Where is the field "type" to manage address?

Hello.

For V7.0 we will not have officially res.partner.address, but, we need for legal reasons to have an specific address of type "Invoice" and this address is ona and just one per company in Venezuela, and other options for Mexico, in MX we need mark specifically the invoice address to use in electronic invoicing.

Functionally and technically how will we manage this feature already in 6.0 and 6.1 on V7.0?

Thanks friends.
