CL 5.7 Multiple messages in one file converted to Edifact

Anyone with experience in converting multiple proprietary messages within one file into several Edifact message also within one file ?

It is a bit like gc_buildEDIinterchange.tcl except I want to do it in the xlt, because the input format is not Edifact.

The iteration of the proprietary format works fine, but all the messages will be transferred to the same area in the original Edifact format because it can not iterate.

I changed the Edifact format so the message can iterate by the use of the UN/EDIFACT configurator. Every time I try to use this variant, it blows up in my face with:
