years to be approved by EU member states plus quite some years to possibly be adopted by industry. I can see allowing for the possibility of the new version, but I don’t think we ought to prevent the current method from being used, even though it does have
shortcomings addressed by the new version. I think any OPC-specific requirements we add can be specified in a manner that is XAdES version agnostic. For example, the ones in the draft text we looked at in Bellevue that were based on MS-OFFCRYPTO and ODF.
I think the normative references could allow both XAdES. This is a good topic for broader discussion.</span><o:p></o:p></p>
