the bank response, may lead double-submission even if the HTTP talk ended
well: it suffices to crash after having received a "200 OK" response but
before setting the submitted flag to the database.

+* Given that PostFinance does not provide the IBAN & BIC pair
+ on HTD (or other "admin" message types), the client cannot
+ confirm the bank account metadata with the bank. As a result,
+ it can only rely on what the configuration has in the
+ ACCOUNT_NUMBER value.
+
+ The current design however does NOT mandate any particular
+ format for such configuration value, and given that the debtor
+ BIC is mandatory in the pain.001 generation, ACCOUNT_NUMBER
+ should be a Payto address with BIC and account holder name.
+
+ Possibly, it may even be renamed to better match its content,
+ for example to ACCOUNT_METADATA.
