Unclear if this is an issue in zeep, the wsdl, or a gap in my understanding

Hi all, forgive the vague example here as this is relating to work so I'm not comfortable copy pasting verbatim.

Given a method that accepts a complextype object, it seems like if I render the fully built object as XML via lxml.etree.tostring() then the XML reflects the structure of the data, e.g.,:

<ParentObject>
    <SubsidiaryObject>
        ....
    </SubsidiaryObject>
    <SubsidiaryField>value</SubsidiaryField>
</ParentObject>

But if I submit an order via client.service.method() using the same object that yielded the above, and retrieve the SOAP envelope from history.last_sent and render it to XML also with lxml.etree.tostring() then what I see is this:

<soap-env:Envelope>
    <soap-env:Header>
        ...
    </soap-env:Header>
    <soap-env:Body>
    <SubsidiaryObject>
        ....
    </SubsidiaryObject>
    <SubsidiaryField>value</SubsidiaryField>
    </soap-env:Body>
</soap-env:Envelope>

That is, the <ParentObject> tag is stripped.

I'm pretty new to SOAP so I don't understand if this is an intentional nuance or something's wrong.

Worked this out-- it seemed it wasn't that tags were being stripped rather than my rendering the XML adding an outer level node that I'd neglected, oops.
