Michael, Taki, members of the EXI WG:

The XML Security WG has been chartered to review use cases and  
requirements related to XML Canonicalization, XML Signature and other  
XML Security specifications in order to update these core  
specifications appropriately [1]. Algorithms, security  and  
performance are of specific interest.

We are very interested in use cases and requirements from the EXI  
working group related to XML Security, as well as any issues you may  
have discovered with the current recommendations.   Is the EXI  
working group able to share any specific security use cases and  
requirements with the XML Security WG? We are currently working on a  
draft requirements document so input would be timely.

In addition, we received a position paper at the Workshop on Next  
Steps for XML Signature and XML Encryption held last year [2]. It  
mentioned two possibilities - signing/verification at the EXI level  
and lightweight signing in general. Is the EXI working group able to  
help us understand these approaches in more detail and the associated  

Thank you

regards, Frederick
