[Already reported to ietf-action [www.ietf.org/rt #149401], I just mention it here so people do not waste time doing it again.] I cannot upload the new version of a draft. .txt has been produced by xml2rfc, without any error message but the datatracker refuses it: An exception occurred when trying to process the XML file: 'X509' object has no attribute '_x509' I have no clue what it can mean.
