That makes it clear.
Actually, I just did not know about inclusions;
they are not in XML.
I just read up on them now.

I have read something on short references.
My undertanding is that you could set up short refences
for architectural variable dereferencing and array access tags
in the SGML Declaration.
Alternatively you could have a single architectural tag for complex
expressions,
again with a suitable short form.
You would probaly want to declare a notation type for this tag.
