Description

Currently there are some longstanding issues with deleting updating documents which contain child documents, there is a workaround by always adding the _childDocuments_ property e.g

curl http://localhost:4003/solr/test/update?commitWithin=3000 -d '
[

{id : 1, _childDocuments_ : []}

]'

Would make sure the child documents are deleted and this works ok.
Except in the XML variant.

<update>
    <add>
        <doc>
            <field name="id">1</field>
            <doc></doc>
        </doc>
    </add>
</update>

It will not work because it will actually try to index it as a child document complaining about missing required fields.
