+-- # - A bar code which is only static, and includes its own security, needs:
+-- # level1Signature
+-- # level1KeyAlg if the associated key does not include the complete certificate in keys.xml but only the public key
+-- # (but level1SigningAlg is not necessary as it is in keys.xml)
+-- # - A dynamic bar code including static and dynamic signatures needs:
