I just formatted a draft using xml2rfc and the online tool, https://xml2rfc.tools.ietf.org/. Then I submitted the result for publication. And it was refused because the submission checking tool https://datatracker.ietf.org/submit/ found 4 errors in the copyright and IPR boilerplate. This is weird, because my draft used the xml2rfc option ipr="trust200902". But it seems that the xml2rfc tool and the submission checking tool disagree. I get an interesting message, complaining about errors such as this one: ** The document seems to lack a License Notice according IETF Trust Provisions of 28 Dec 2009, Section 6.b.i or Provisions of 12 Sep 2009 Section 6.b -- however, there's a paragraph with a matching beginning. Boilerplate error?

As far as I can tell, the only difference between one text and the other are the position of the line breaks. Of course, the line breaks are chosen by the editing tool, and I have no control. Any suggestion on how to fix my draft? -- Christian Huitema
