If your tFromExtension (which I see now, at least in the generated
comment) is supposed to have both content and the sub-element
<literal>, then it must be a complexType/complexContent and have
mixed="true". . This means that you'll have to have mixed="true" on
the derived type tFrom as well. Also, if you derive from the schema
type anyType, you'll imply mixed content. And, as you have
experienced, JAXB somehow fails to unmarshal the elements in the
choice group. I think this is a bug in JAXB.
But do you really need the <from> element to have content? If you
remove the mixed="true" and declare
<complexType name="tFromExtension">
<sequence>
<element
ref="{
http://www.zzzz.com/xmlns/xxxxx/xxxxxxxxxx/6.0.0/}literal"
minOccurs="0"/>
</sequence>
</complexType>
Then, tFrom will have getters for query and the other choices.
