Additional XML Security Uniform Resource Identifiers (URIs)

This document expands and updates the list of URIs intended for use
with XML Digital Signatures, Encryption, Canonnicalization, and Key
Management specified in RFC 4051 (April 2005). These URIs identify
algorithms and types of information. XML Digital Signatures,
Canonicalization, and Encryption have been standardized by the W3C
and by the joint IETF/W3C XMLDSIG working group. All of these are now
W3C Recommendations and IETF Informational or Standards Track documents.
All of these standards and recommendations use URIs (RFC 3986) to
identify algorithms and keying information types. This document is
a convenient reference list of URIs and descriptions for algorithms
in which there is substantial interest but which can not or have not
been included in the main documents for some reason. Note in particular
that raising XML digital signature to Draft Standard in the IETF
required remove of any algorithms for which there was not demonstrated
interoperability from the main standards document. This required
removal of the Minimal Canonicalization algorithm, in which there
appears to be continued interest, to be dropped from the standards
track specification. It was included in RFC 4051 and is included here.
