presentationSubmission

OID4VP: REQUIRED. The presentation_submission element as defined in DIF.PresentationExchange. It contains mappings between the requested Verifiable Credentials and where to find them within the returned VP Token. This is expressed via elements in the descriptor_map array, known as Input Descriptor Mapping Objects. These objects contain a field called path, which, for this specification, MUST have the value $ (top level root path) when only one Verifiable Presentation is contained in the VP Token, and MUST have the value $[n] (indexed path from root) when there are multiple Verifiable Presentations, where n is the index to select. The path_nested object inside an Input Descriptor Mapping Object is used to describe how to find a returned Credential within a Verifiable Presentation, and the value of the path field in it will ultimately depend on the credential format. Non-normative examples can be found further in this section.
