New functionality added to Odoo
This update adds support for the Hacienda Foral de Navarra tax agency within Odoo's SII invoicing system. It addresses a specific requirement for explicit XML namespace declarations, ensuring correct invoice submission to the Navarra SII system. This expands Odoo's compliance with Spanish tax regulations.
Original PR description
The Hacienda Foral de Navarra uses the same SII XML format as AEAT but sends invoices to a different endpoint. Additionally, Navarra requires explicit XML namespace declarations in the SOAP envelope header, which the standard zeep serializer does not include by default. This adds the Navarra tax agency as a new option in the company SII configuration, defines its production and test endpoints, and injects the required namespaces in the request header when the Navarra agency is selected. task-5946583 I confirm I have signed the CLA and read the PR guidelines at www.odoo.com/submit-pr Forward-Port-Of: odoo/odoo#263048
