The following packages may be useful as an alternative to or used in
conjunction with PyXB:
The Zolera SOAP Infrastructure is the backbone of the
Python Web Services project. It is
specifically intended to support web service interaction with SOAP and
WSDL. The primary purpose of ZSI is SOAP, but it generates bindings for
some XML Schema constructs. The last release of ZSI appears to have been
in 2007, so much of this paragraph could be reworded to be in the past
tense.
generateDS is an
alternative package that is intended to do the same general thing as PyXB,
though it uses a very different approach for extending bindings.
generateDS is still under active development/maintenance.
