Belated introduction

I was reminded that I hadn't sent an introductory note to the list.  So 
here it is...

I'm John Wray; I work In IBM's Datapower group, developing our line of 
XML-based network appliances.  The appliances implement XML-DSig, 
XML-Encryption, and pretty much anything starting with either an "X" or 
"WS-".  Most recently I've been working on various aspects of conformance 
with WS-I profiles.  I've been in the security field for quite a time, and 
while I've been involved with several IETF working groups before (mostly 
in the areas of authentication and PKI), this is my first time in a W3C 
WG.
