Web Crypto WG and XKMS

Hi
Looking at http://www.w3.org/wiki/IdentityCharter#Web_Cryptography_Working_Group_Charter
"The goal of this Working Group provide standards around key storage
and cryptographic primitives that will provide capabilities that are
currently difficult to do safely on the Web platform. "

(+1 on the new name btw)

How does this relate to the earlier XKMS work?
http://www.w3.org/standards/techs/xkms#w3c_all

e.g. http://www.w3.org/TR/2005/REC-xkms2-20050628/
Abstract: "This document specifies protocols for distributing and
registering public keys, suitable for use in conjunction with the W3C
Recommendations for XML Signature [XML-SIG] and XML Encryption
[XML-Enc]. The XML Key Management Specification (XKMS) comprises two
parts — the XML Key Information Service Specification (X-KISS) and the
XML Key Registration Service Specification (X-KRSS)."

It seems the latter emphasises protocols (and hence leans more towards
SOAP/WSDL than APIs), while the former emphasises in-browser APIs, but
they share a concern for key storage and management?

Are there any pieces of work that can be shared across these use cases?

cheers,

Dan
