Rémy,
Here is that fix I mentioned.
This fix basically says: Go ahead and keep on processing (the
following steps of the process) even if there are error or warning
messages. We want it to do that because, in the case of wmdr.xsd,
there are warning messages that we want to ignore, and I can't, in
general, distinguish between warning and error messages, ignorable
messages, etc.
I was concerned that (1) the user might make changes to the XML
schema, (2) the schema might cause generateDS.py to fail to generate
the library/module, and (3) the django file generation process might
use a previously generated library/module without the user noticing
it. With this fix, we clean up and delete those files (the module
itself and both Python 2 and Python 3 compiled/pyc files). Then, if
generateDS.py does fail, that will cause a failure at a later stage,
and the user will forced to be aware of it.
A patched file is attached. Let me know if this works for you.
I'll try to do some more testing, some clean up, and create a new
release in a few days.

Synopsis:
Generate Django models.py and forms.py from XML schema.
Usage:
python gends_run_gen_django.py [options] <schema_file>
Options:
-h, --help Display this help message.
-f, --force Overwrite the following files without asking:
<schema>lib.py
generateds_definedsimpletypes.py
models.py
forms.py
-p, --path-to-generateDS-script=/path/to/generateDS.py
Path to the generateDS.py script.
-v, --verbose Display additional information while running.
-s, --script Write out (display) the command lines used. Can
be captured and used in a shell script, for example.
Examples:
python gends_run_gen_django.py my_schema.xsd
python gends_run_gen_django.py -f -p ../generateDS.py my_other_schema.xsd
