Hi, I'm desperately trying to construct an XML with the following document
declaration:

<Document xmlns=3D=E2=80=9Durn:iso:std:iso:20022:tech:xsd:pain.008.001.02=
=E2=80=9D
        xmlns:xsi=3D=E2=80=9Dhttp://www.w3.org/2001/XMLSchema-instance=E2=
=80=9D>

I'm using LXML, and what I'm doing is this

>>> from lxml import etree
>>> from lxml.builder import E
>>> doc =3D E.Document(
...     {
...         'xmlns': "urn:iso:std:iso:20022:tech:xsd:pain.008.001.02",
...         '{xmlns}xsi': "http://www.w3.org/2001/XMLSchema-instance",
...     }
... )
>>> print etree.tostring(doc)
<Document xmlns:ns0=3D"xmlns" ns0:xsi=3D"
http://www.w3.org/2001/XMLSchema-instance"
        xmlns=3D"urn:iso:std:iso:20022:tech:xsd:pain.008.001.02"/>


I've tried everything I can imagine and this is the best I can do :(

Any idea on how to get the xmlns and xmlns:xsi attributes correctly?

Thanks!!
