allows the user to interact directly with XML schemas. My code loads a
schema and creates a JDOM tree just as if it were a normal XML document.
However, here’s the problem: I’m trying to get the include child
elements from the root element but always the list I’m returned is
empty. Checking using the NetBeans debugger shows that the JDOM Document
object matches the underlying schema.</span></font></p>
