[Xml-compile] Fault when required child within optional parent node

[Thibadeau, Daniel]

Thanks for the quick response.  You were exactly right, the response contained an empty <payment_information/>   element.  I'll talk to the server owner to fix.

Now that you pointed it out it seems obvious.  I was looking in the wrong place.  I did learn a lot reading through your code looking for hints.  I haven't used "closures" before, but will be playing around with them for days to learn more :)

Yes, decoding is performed on the received message.  Also, the element named *Response.

I expect that the response contains an empty <payment_information/>   But
it may also be not empty with an unexpected or out-of-order field.

See $trace->printResponse(pretty_print => 1);

Fix the schema or server ;-)

The first error is only the last (fatal) issue.  After that, it lists all issues, sometimes with more information.
