* All the test for LITAS-PHA in file *EN_SCT Ver 2017-10-10_SCT Testing Tasks for CENTROlink applicants_EN* are readacted - does it mean there is no need to process [BALANCE message](Messages/BALANCE) other than to save the documents it contains in [CDR](Architecture/CDR)?
* What kind (if any) authentication is expected for message-receiving web services on [CPR](Architecture/CPR) side?
* BoL seems to be using [XAdES 1.1.1](http://www.w3.org/TR/XAdES/), but all existing libraries (XAdEs4J, DSS, SecureBlackbox) seem to only support [XAdES 1.4](http://uri.etsi.org/01903/v1.4.1/) - are the newer versions of the standard backwards compatible with the old ones?
