Routing Details (vrbl:RoutingDetails)

VRBL messages will be used to exchange electronic compliance documents. Three elements are required to correctly route (aka 'process') messages. The elements consists of:

• unique sender id
• unique receiver id
• unique document type id (provided in the Specification Identifier)

Based on these elements, the provider invokes actions such as message conversion from the VRBL format to the right target format or vice versa, digital signing of messages, message delivery via APIs to governmental institutions etc.

In VRBL the unique sender id and receiver id are provided in the following extension on the document level.

For inbound messages the basic value will be extended to contain also the document type and the code identifying the ruleset which applies to the document.

Example: Outbound Payments document indicating the MX Tax Authorities (SAT) as technical receiver of the document.
