commit cbe4ce3f2853b4113d0550396a9b37b3bdc7bec2
Author: MS <ms@taler.net>
AuthorDate: Sat Jan 7 14:03:47 2023 +0100

    Tests.
    
    Testing that some pain.001-valid amounts
    are still rejected after the XML validation.
    That happens because pain.001 allows more
    than 2 fractional digits, whereas Taler has a
    limit of 2.
