Thanks Island. I'm new to the forum and wonder if I'd get a quick reply. When you mentioned that the worx example is bad, what do you mean by that? Recursive elements seem like a valid concept. If I had a machine that had a function and a subfunction and a subfunction within that subfunction, it seems to me that recursion is the only way to describe that variable hierarchy.
I'm lost. I tried A and B below. If I do get a good xml doc, will it validate?
A.

<Function Function_Name="SubFunction2"></Function>
</Function>
<Function Function_Name="Func3"></Function>
</Functions>

I created a schema that has recursive nodes. I used this example from wrox.
Wrox sample
The file validates, but when I try to have XMLSpy create a sample xml doc, a window briefly appears....then shuts down.
Any ideas?
Thanks.
Steve
