Interlineation
When a word or phrase is presented above another in the main line of text, use interlineation mark-up.
Capture using subsGroup with an attribute role="interlineation", a subsItem with class="primary" and a second subsItem with class="other" and role="interlineation" (which contains the text above the line).
<line>whyle I vnknown in <subsGroup role="interlineation"><subsItem class="primary">[darkest]</subsItem><subsItem class="other" role="interlineation">blackest</subsItem>
</subsGroup> shadowes ly </line>
When multiple occurrences of interlineation occur on a single line, capture each occurrance in a subsGroup.
<line>Evening <strikeThrough>,</strikeThrough> strain <subsGroup role="interlineation"><subsItem class="primary">
<strikeThrough>ed</strikeThrough>
</subsItem><subsItem class="other" role="interlineation">s</subsItem>
</subsGroup>
<subsGroup role="interlineation"><subsItem class="primary">
<strikeThrough>into</strikeThrough>
</subsItem><subsItem class="other" role="interlineation">to be</subsItem>
</subsGroup> dark, <subsGroup role="interlineation"><subsItem class="primary">^</subsItem><subsItem class="other" role="interlineation">to be</subsItem>
</subsGroup> dronedark, | womb-of-all, home-of-</line>
Interlineation can also be nested, where the interlineated text itself has interlineation. This can be captured by using a new subsGroup for the nested interlineation within the subsItem class="other" role="interlineation".
