public class CAdESLevelBaselineLTA
extends CAdESLevelBaselineLT

This class holds the CAdES-A signature profiles; it supports the later, over time _extension_ of a signature with id-aa-ets-archiveTimestampV2 attributes as defined in ETSI TS 101 733 V1.8.1, clause 6.4.1. "If the certificate-values and revocation-values attributes are not present in the CAdES-BES or CAdES-EPES, then they shall be added to the electronic signature prior to computing the archive time-stamp token." is the reason we extend from the XL profile.
