In xforms-submission.xpl (the implementation of
oxf:xforms-submission), the default instance should be the same as the
response instance.

I see in your next message that you now have a solution.

This said, I think a solution to the above would probably be to always
store the result as text first with replace="text", but also store the
result content-type, and then use saxon:parse() to produce actual XML
if the content-type is XML. The main issue as you pointed out is that
oxf:xforms-submission uses only one instance for input/output (except
in the case of shared instances but that's another story):

https://github.com/orbeon/orbeon-forms/blob/master/src/resources-packaged/ops/xforms/xforms-submission.xpl

xforms-submission.xpl could be improved to do this better I think.
