Thanks for your reply, Mike!
I also had that idea of SafeUntrap but after putting in "require" I had 
to untrap "caller", then "-d" and at this point interchange dropped out 
processing interchange.cfg.

That's it !!
I got some real good explanations from Kevin about Safe.pm's supremacy 
*g* in any [perl], [mvasp], [calc] definitions. So, putting the Tag-call 
outside of any of these embedded-perl Tags is the running method I 
searched for so long!
The only small drawback is the [tmp result][your-xml-parser-tag][/tmp] - 
construction to get the return values in following [mvasp]- or [perl]- 
chapters.

Understanding the inner functionalities of interchange (and perl) is 
really strong meat and sometimes frustrating! %-)
But it's fascinating how powerful interchange is!

Thanks again for your help!
