What does Overflow say exactly?

It's not that much that the XML would be bad in itself, but the fact that there
could be a missing connexion or something like that. An incomplete Overflow
network is OK as far as the Overflow libs are concerned... as long as you don't
try to run it. Normally, Overflow shouldn't crash because of those errors, but
hey, there's still some error handling to complete... Could you send me an XML
file that causes problem with Overflow, so I can tell you if the problem is with
the Overflow libs or the GUI?

What do you mean by "how to structure Overflow nodes together"?
