It seems this pull request passed all checks. For some reason locally I'm getting:

Failed to load nl.begra.yml template:
while parsing a block mapping
  in "<unicode string>", line 5, column 3:
      amount: Totaal EUR incl[.] btw\s ...
      ^
expected <block end>, but found '{'
  in "<unicode string>", line 12, column 14:
      iban: [A-Z]{2}\d{2}?\w{4}?\d{4}?\d{4}?\d{0,2}
                 ^

@bosd: please kindly check #447

Implementing a template checking mechanisme is still a to do :)
