Version 2.4.0 from pypi
Expected:

<rsm:CrossIndustryInvoice xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:qdt="urn:un:unece:uncefact:data:standard:QualifiedDataType:100"
xmlns:udt="urn:un:unece:uncefact:data:standard:UnqualifiedDataType:100"

Details

[VD-Valitool-14]-Der Namespace xmlns:qdt fehlt. Auch wenn dieser in der Instanzdatei nicht benötigt wird, sollte dieser gemäß Spezifikation angegeben werden.

did I forgot something to initialize or is it a failure?

Probably a bug, but maybe hard to fix if the XML library we use only adds namespaces that are needed

Thanks for the answer.
In the moment i’m using a workaround. After creating the XML and before attaching it to the pdf i use a brute force method to add the namespace i expect if it doesn‘t exist.
ValiTool has no more problems with this.

I'm also interested in a solution to this validator error. How do you add namespaces after creation? Just with text based file manipulation?

from drafthorse.models import NS_QDT
….
xml = self.modify_xml(self.doc.serialize(schema="FACTUR-X_EXTENDED"))
….

def modify_xml(self, xml=None):
        """insert xmlns:qdt if it is not in namespaces"""
        decoded = xml.decode('utf-8')
        searchstr = re.search(r'<rsm:CrossIndustryInvoice(.*)>',
                              decoded).group()
        # print(searchstr)
        nsmap = searchstr.split(' ')
        _QDT = 'xmlns:qdt='
        if _QDT not in nsmap:
            QDT = _QDT + '\"' + NS_QDT + '\"'
            nsmap.insert(1, QDT)
            decoded = decoded.replace(searchstr, ' '.join(nsmap))
        # print ('MAP:', nsmap)

        return decoded.encode('utf-8')

Thank you for the pointer. Your if statement does not work when attribute is present, so I modified that part to

    _QDT = 'xmlns:qdt='
    QDT = _QDT + '\"' + NS_QDT + '\"'
    if QDT not in nsmap:
        ...

[lka]

you are right, thanks
