Thank you very much for your help. I'm not sure about the schema
or the samples, but I would guess that they worked in some xml
parser somewhere.
I see that the schema used in pyxbgen should be SAA-Message.xsd
instead of SAA-Feature.xsd. With that change, it gets the error
shown below. Is there a way to turn on debugging or set verbose
to see what it is complaining about?
Thanks again,
Wendell
