Andrew -
Ah. Default value plus simpleType. OK. ... I think I've fixed
that now.

The code generated by generateDS.py does not automatically check
values specified in a restriction. However, if you have a need for
this, take a look at the section "simpleType and validators" in the
documentation:
http://www.rexx.com/~dkuhlman/generateDS.html#simpletype-and-validators
I believe that I've also fixed the problem related to the following
message that you reported:
"Element assignment extension chain contains mixed and
non-mixed content. Not generated"

With the attached patch, you should see generated code that
initializes to the default value.
So here is a summary of changes:
* Fix for exception with simpleType that is an extension of
another simpleType.
* Change to mixed extension chain -- Will now generate class.
* Fix to generation of constructors -- Will now initialize to
default value for simpleTypes.
* Fixed generations of validator methods, validator bodies,
and call to validator bodies for attributes.
A patch file that can be applied to generateDS.py version 1.18a is
attached.
Let me know how that patch works. If it seems OK, I'll try to upload a
new version tomorrow or the next day.
