This update allows other Odoo modules to customize the criteria used to define SLAs (Service Level Agreements) when creating helpdesk tickets. Previously, this customization was limited, but this change expands flexibility and improves the ability to tailor SLAs to specific business needs. It builds on existing functionality for related domains.

Allow other modules to modify the _sla_find domain when adding SLAs to helpdesk tickets.

This is already the case for extra and false domains, while the main domain is hardcoded up to this commit.

This update enables users to send multiple attachments when sending invoices through the Peppol network. The attachments are now embedded within the invoice XML file using a standard 'AdditionalDocumentReference' tag, improving the efficiency of electronic invoice exchange. This enhancement aligns with Peppol standards and simplifies document handling.
