MINUTES FROM EUROPE ASIA UBL WORKING SESSION WEDNESDAY 6th JULY at0800 UTC

Attendees:
Tim McGrath
Thomas Lee
Peter Borresen

Given the limited attendance, we decided to concentrate this meeting on 
the topic of Digital  Signatures.  Peter and Thomas have an action tiem 
to prepare a white paper on this issue.

TL: outlined the requirements from the Certificate of Origin document.   
This document is actually built up in stages by different orgnaizations, 
each of whom signs their respective parts.  This also means the sequence 
of signing is significant as well.

Two approaches have been identified:
a. encapsulating the digital signature inside the document (the Crimson 
Logic approach)
b. referencing the digital signature from the document and storing it 
externally (the DTTN and ebXML approach).

Both have their strengths and weaknesses.

Action Item: Peter will create a draft of how the Digital Signature 
could be referenced from a UBL document and pass to Thomas for his input.
