This is very, VERY likely as this is my first XML application. That's why
I mentioned that I had to edit the file to get things working.

This I figured out.  The XIncluded portions were not important to what I
was trying to accomplish at the time so I just cut those pieces out.

I thought I followed the guidance in "XML in a Nutshell" fairly well, but 
perhaps I didn't.  Here are some fragments from my XMLSchema-instance 
document and my XMLSchema document.  Anything stand out as erroneous?

                The "apprentice_tasks" element is the root-level element for 
an
                apprentice document.  It contains the task descriptions and
                topic maps that are used to dynamically assemble tutorials.

                        Each "task" element fulfills one of two roles:  it is 
either
                        a meta-level task-of-tasks organizer or a description 
of how
                        to accomplish a particular goal using a particular 
tool or
                        technique.
