Don't classes generally need to be contained in a Package or Model or
something like that?

Hi

The Indigo version of Superstructure.uml starts

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.1"
xmlns:xmi="http://schema.omg.org/spec/XMI/2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:Ecore="http://www.eclipse.org/uml2/schemas/Ecore/5"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore"
xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML"
xsi:schemaLocation="http://www.eclipse.org/uml2/schemas/Ecore/5
pathmap://UML_PROFILES/Ecore.profile.uml#_z1OFcHjqEdy8S4Cr8Rc_NA">
<uml:Model xmi:id="_s-vBgBjPEdqPB8O80Bm3OQ" name="UML">

demonstrating that the root element is a Model and that the namespace is
http://www.eclipse.org/uml2/3.0.0/UML rather than ...omg... It differs
variously becuase OMG URI policy has been evolving and because an Ecore
prpfile is applied.

The file is readable by the UML model editor so you can debug that
editor to compare it with your code.
