Brian Curtin added the comment:
This is something that should be handled on the trackers of any of the external
SOAP libraries. If they are ported to Python 3 and are seen as best in class
and are willing to move all development into the standard library, then
inclusion could be considered.
New submission from Michiel Van den Berghe :
There doesn't seem to exist a SOAP library for Python 3.x. Several different
third party libraries exist for the 2.x releases, but none of these are being
ported to 3.x. None of these modules are easily ported using 2to3 due to string
encoding issue
