Metadata test md common req C.13: given error text is not correct

[PeKoNW]

In contrast to test md common req C.12 the subject here is the date of last revision.
But the given error text at the bottom says e.g.: The metadata record set has 1 record(s) with errors for this assertion.
XML document 'service.xml', record '7194db84-179c-457d-89cf-4277a02e5654': A metadata record must not have more than one creation date (within its identification information). The metadata record does not fulfill this requirement.
I assume the error text was copied from the C.12-test and involuntarily not maintained.
