Hi there Murata-san, 

 

Below, you wrote, “We are committed to the introduction of XAdES EN into the OPC revision.”

 

I’m asking for clarification of this statement, so it is not misunderstood. At a glance, it seems to be making a broader claim that I thought WG4 had agreed to.

 

>From the Barcelona meeting minutes: “On Tuesday, in WG4 discussions: There was consensus that we should produce an informative annex describing a profile for XAdES appropriate for use with OPC, and allow for both DigSig 1.0 and 1.1 in the text.”

 

When this was agreed to, it was my understanding that there would *not* be any mandatory normative text re XAdES in the new OPC spec. Instead, the informative profile would give directions as to how an implementation could support XAdES, if it chose to do so. Specifically, a conforming implementation of the next edition of 29500-2 need *not* provide any support for XAdES at all.

 

Sure.  An OPC package with XML digital signatures does not have to 

use XAdES.  But to allow the use of XAdES EN, we have to allow the 

use of XML DSig 1.1 in OPC.   In other words, if the revised OPC spec 

use XML DSig 1.0 rather than DSig 1.1, I think that the use of XAdES 

EN will be prohibited. 

 

Regards,

Makoto

Subject: DR 11-0030: Proposal

 

DR 11-0030 - OPC:  Obsolete version of W3C XML Digital Signature 1.0

https://skydrive.live.com/view.aspx/Public%20Documents/2011/DR-11-0030.docx?cid=c8ba0861dc5e4adc <https://skydrive.live.com/view.aspx/Public%20Documents/2011/DR-11-0030.docx?cid=c8ba0861dc5e4adc&sc=documents> &sc=documents

 

This DR requests a change in the normative reference of Part 2 §3 from XMLDSig 1.0 (http://www.w3.org/TR/2002/REC-xmldsig-core-20020212/) to XMLDSig 1.1 (http://www.w3.org/TR/xmldsig-core1/).

 

We are committed to the introduction of XAdES EN into 

the OPC revision.  XAdES EN uses XML DSig 1.1 

rather than 1.0.  I thus believe that we cannot stick 

to DSig 1.0.

 

Regards,
Makoto
