Additional XML Security Uniform Resource Identifiers (URIs)

This document updates and corrects the IANA registry for the list of URIs intended for use with XML digital signatures, encryption, canonicalization, and key management. These URIs identify algorithms and types of information. This document corrrects three errata against and obsoletes RFC 6931. The intent is to keep this draft alive while it accumulates updates until it seems reasonable to publish the next version.
