Re: [Generateds-users] GenerateDS Question -- django and Python 3

[Dave Kuhlman]

Shane,

Is there something in the XML schema that would tell us that we need
to generate the chances you had to make by hand?  If so, could you
share your XML schema with me, or at least the element definition
that you are talking about?  If I had the schema, I would
hopefully able to try to generate the changes that you made
manually.

Dave
