<did>
                     <unittitle>Files</unittitle>
                     <container id="cid172002" type="Box" label="Text">8</container>
                     <container id="cid172001" type="Box" label="Mixed materials">19</container>
</did>

And it's evaluating both of those type="Box" as unique even though they're not. If I understand correctly, this is because it's not looking at sibling containers but rather only at later non-sibling containers, yes? And since it's the end of the document there are no non-sibling containers below it in the tree, hence nothing to compare to, hence they all appear to be unique?

What's the best way to fix this?
