Dear all,
I copy below my reply to another comment that Peter Sylvester made

Are you thinking in the linking time-stamps mechanisms defined
in ISO?

One suggestion, Peter, perhaps you could send a copy of your emails to the
list that the DSS TC has for public comments:

dss-comment@lists.oasis-open.org

In that way, all the members of the TC will see your emails and be able to 
answer.

Regards

Juan Carlos.
