Thank you for the link.

In Heron it is not a problem, Heron links during compilation.

I want the XML to represent only fullly legal and valid programs. The goal
is to have the XML format be as easy to work with for a third party as
possible, if the XML is known to be valid that simplifies the work of the
final stage translator.

The source is in Delphi, but since my original post I have put the XML
generation on hold temporarily. I am very interested in collaborating on an
intermediate XML format. I have already designed a big part of it, and I
would be interested in knowing what it would take to make the format
interesting to you and to others.
