From reactions I understood that other people are interested in this subject of \xmlinclude too, but at that moment I could not produce a coherent story.
After having produced some minimal (1) working, (2)  not working and (3) crashing examples, I dare hope that my contribution of these will be of some use. And perhaps they will spawn better suggestions and better understanding of what happens, because I must confess I am somewhat unsure with functional language behaviour, being raised with Assembler, Algol, Pascal, Fortran, and so on ;-)

Find below my examples. One can call each of them by commenting out the \starthiding.
The last one can be executed by removing the %%%%'s at the front of the offending statement.
Again, I hope this post will be of some use.
