Thanks @asmecher,
That makes sense to me, but I have tried adding id="6", current_publication_id="6" and publication_id="6" but it always gives a validation error because that attribute is not allowed.
I have read your post about the two important XSD files that define the XML schema (NativeXML validation errors - #4 by asmecher) and between the attributes of publication I don’t see any id listed except primary_contact_id.
Do you think I’m doing something wrong?
Kind regards,
Daniel
