Re: [pyxb-users] generating xml documents from python instances

[Peter B. <bi...@ac...>]

The ns1 annotations occur because your schema specifies that the elements
are in the urn:iso:std:iso:20022:tech:xsd:pain.008.001.02 namespace.  See
http://pyxb.sourceforge.net/userref_usebind.html#creating-xml-documents-from-binding-instancesfor
information on how to control the namespace qualifiers.  Search the
provided examples or the mailing list archive for ways to set the default
namespace when generating documents, which would eliminate the qualifiers on
most elements and attributes.

FWIW, the namespace qualifiers are required to produce valid XML, and are
unrelated to whether your document validates.
