Thanks!

Yes. PDF specification doesn't say anything like that. It just defines
that \r and \n are EOL markers and if they are used in a sequence they
are treated as a single EOL (e.g. \r\r or \n\n is treated as a single EOL).
So this looks like a PDFA specific requirement. (Btw. I have checked the
PDF specification PDF and it uses single \r as an EOL)

Yes, I guess so.
