Dear Mr Jolliffe,
I am writing on behalf of the OASIS DSS-X TC in response to your email
of 14th August 2008.
First of all, the DSS-X TC wants to thank you for the submission of the
aforementioned email.
From the review of the specific questions that you include in your
email, it is the opinion of this TC that questions #1, #2, #3 and #5
actually are more related to the XAdES standard itself than to the DSS
profile for managing generation and verification of XAdES sigantures
produced by this committee. It is the opinion of this TC that ETSI
Electronic Signatures and Infrastructures (ESI) Committee is the
suitable body to answer them.
As for question #4, as you notice, DSS produced and DSS-X is producing a
number of profiles for matching the DSS core standard to specific
environments or to incorporate new features. The DSS set of standards
also allow to combine different profiles incorporating additional
features for obtaining more powerfullness.
This approach allows to incorporate in the core a set of basic yet
relevant features, and still allowing that those systems requiring
additional ones may make use of the profiles.
