It would be helpful to see the error messages you get from XSD
as well as your schemas.

I would definitely like to get the schema that reproduces this.

No, you should be able to use your schemas regardless of the names
you use. Perhaps you are trying to use the example driver (driver.cxx)
from the hello example with your schemas. Now that won't work. You 
will need to change it to correspond to your XML vocabulary.

There is a number of examples in the examples/ directory in the XSD
distribution. The 'library' example might be a good starting point.
Also, if you want to see real-world schemas, you can find some on 
this page:

XSD is able to handle element references without any problems as long
as the element name is actually defined (otherwise you will get an
error). I am pretty sure there is something wrong with your schemas.

Also, if you would like a quick introduction to XML Schema, you may
find this document useful:
