Here is my understanding (I'll double check with the engineer when he gets
in).
LTV enabled means that all information necessary to validate the file
(minus root certs) is contained within. So this statement of yours would
be true.
the PDF is signed correctly and contains all necessary certificates,
a valid CRL or OSCP response for every certificate
But since the only way for that statement to be true is for the presence
of DSS, you must have DSS for LTV-enabled to appear. No timestamp
(regular or document level) is required.
