A data storage facility for Additional Data. The ADR dereferences a URI passed in a SIP Call-Info header field or PIDF-LO <provided-by> element and returns an Additional Data object block. It replaces and deprecates the concept of CIDB previously defined in 08-003 v1. ADR is considered a Functional Element (FE).
