@jmandel I took `referenceRange`s out for the moment. You included CCDA `referenceRange`s in https://github.com/blue-button/bluebutton.js/pull/69#discussion_r6845109 that looked like:

```
<referenceRange>
  <observationRange>
    <value xsi:type="IVL_PQ">
      <low value="4.3" unit="10+3/ul"/>
      <high value="10.8" unit="10+3/ul"/>
    </value>
  </observationRange>
</referenceRange>
```

But AFAICT those aren't formatted the same in C32. As best I can tell from http://motorcycleguy.blogspot.com/2012/08/moving-on-from-c32-lab-results.html and C32 files I've looked at, they look like:

```
<component typeCode="COMP">
    <observation classCode="OBS" moodCode="EVN" negationInd="false">
        <templateId root="1.3.6.1.4.1.19376.1.5.3.1.4.13"/>
        <templateId root="2.16.840.1.113883.3.88.11.83.15"/>
        <templateId root="2.16.840.1.113883.3.88.11.83.15.1"/>
        <templateId root="2.16.840.1.113883.10.20.1.31"/>
        ...
        <referenceRange>
            <observationRange>
                <text>&gt;=105.0</text>
            </observationRange>
        </referenceRange>
    </observation>
</component>
```

That seem right to you? If so I'll add these back in.
