xsd:choice Metadata Missing?

[gingerrunner-55]

Opening up an xsd and processing as follows, using version 25.7 of xsdata:

config = GeneratorConfig()
transformer = ResourceTransformer(config)
transformer.process_schemas([xsd_schema_path.resolve().as_uri()])
for xsd_class in transformer.classes:
    *bunch of code*

For context, the plan is to convert the pieces of xsd_class into an existing intermediate representation for codegen in other languages. I currently have an implementation that does this with xmlschema, but the code is extremely hacky around the handling of xsd:choices, and my bandaids have limitations.

One of the classes in question is represented in the xsd, simplified, as follows:

<xsd:complexType name="ClassA">
    <xsd:sequence>
        <xsd:element name="one" type="typeOne"/>
        <xsd:choice>
             <xsd:element name="two" type="typeTwo"/>
             <xsd:element name="three" type="typeThree"/>
        </xsd:choice>
    </xsd:sequence>
</xsd:complexType>

Looking around in an IDE, the Class def of ClassA nor the attributes of two and three, I don't see any indications of a choice grouping or that two/three are a part of a choice.

I've tried compound_fields, no dice, perused the other issues and I don't see anything that matches my issue that hasn't been resolved already. But I don't see what I'm missing for getting this information out, which is vital for our intermediate representation,

On a side note, this library is awesome, and if this can be worked out it'll be leagues better than my existing code.
