[Leticia Larrosa]

Hi all:

I have three aspect to ask

1- how can generate automatically a WSDL from python code that represent a 
web services?
exists any tool? I know about tools for java or perl, but i can't find 
anything for python

2- if i want to pass and "xml document" in a soap or xml-rpc message i know 
three options:

- can be passed as a single quoted string 
- pass like a attachment for the SOAP message
-the fields can be passed as separate parameters (option that i can't use)

exists any else options? 
the SOAPPy library don't support the  attachment, anybody know about other 
library that support it?

3- exists other mailling list to discusess this topics? any suggestions?

thanks in advance
