The critical part you are missing is that the attribute type=vga and the
group containing attribute type=qxl need to be within a choice element.
That is:

    <element name="model">
      <choice> <!-- this is important -->
        <attribute name="type">
          <choice>
            <value>vga</value>
            ...
          </choice>
        </attribute>
        <group>
          <attribute name="type">
            <value>qxl</value>
          </attribute>
          <optional>
            <attribute name="ram"/>
          </optional>
        </group>
      </choice>
      ...
