JSContact: Converting from and to vCard

This document defines how to convert contact information between the JSContact and vCard data formats. It defines conversion rules for every JSContact and vCard element registered at IANA at the time of publication. It also defines new JSContact properties as well as vCard properties and parameters, to support converting arbitrary or unknown JSContact and vCard elements. This document obsoletes RFC 9555 and updates its definitions for JSContact version "2.0". Note This note is to be removed before publishing as an RFC. Differences from RFC 9555 are documented in Appendix A.
