George,
Thanks for reporting this. And, thanks for doing that preliminary
work to track it down.
I generated code from enum-list.xsd, and I believe I have been able
to re-create the same error you report.
I've been working recently on an enhancement to generateDS.py to
generate validation code for a defined simpleType. As part of that
work, I implemented a function (find_simple_type_def) to find a
simpleType definition in the input schema. That new code is now at
BitBucket:
https://bitbucket.org/dkuhlman/generateds/overview
If you're right about annotate_find_type(), then perhaps using that
newer technique in find_simple_type_def could help us there, also.
The new code uses xpath, which requires Lxml, but I'm pretty sure
that generateDS.py requires that (instead of ElementTree) to run
successfully anyway.
I'll take a look. Hope to have something to report next week. If
you learn anything more, let me know.
Dave
