Description
We're encoding certainty like this:
<lb n="060004"/><said xml:id="060004-a" who="Cunningham">―Come on, Simon.
<certainty target="#060004-a" match="@who" locus="value" assertedValue="Power" degree="0.5">
<desc>It's unclear here whether it's Cunningham or Power speaking.</desc>
</certainty>
</said>
...but this obviously shouldn't appear in the transformed HTML output.
Ideally, when displaying the dialogue tags for this, we'd have some kind of dotted line or something to indicate fuzziness.
