Here is the info from my engineer:
1. "a valid CRL or OSCP response for every certificate" also includes
signatures over CRLs and OCSPs., not just the signature certificate.
2. LTV may be enabled when all collaterals are embedded in the
signatures and not DSS (I just fixed a bug that did not handle this case
correctly). In this case there may be no DSS. However, this is very
unusual, because signatures over CRLs and OCSPs do not contain embedded
rev info which is Adobe extension. Yet, this is a distant possibility.
