Keep the same "case" in the class names

[skinkie]

At this moment it seems that xsData is transforming the casing of an element to something "pythonish" would it be possible to keep the "original" element casing as it matches the casing in the XML Schema and obviously the XML itself?

Check the generator config , you can select the name case for classes and fields, set the class name case to originalCase

Below works, for me but when changing FieldName to originalCase as well, I end up with:

In addition to that, the generated code has syntax errors;

I have been using 52, but there is a new source release here: https://www.editeur.org/files/ONIX%203/ONIX_BookProduct_XSD_schema+codes_Issue_53.zip

For the exception during the generation, there is a fix on master for that, thank you for reporting, I guess no-one tried it before for the field names.

For the second part unfortunately that's what the original case is supposed to do, return the original string without any modifications, even if the produced code has syntax errors.

Try one of the mixed cases mixedCase|mixedSnakeCase|mixedPascalCase that protect the original words naming case.
