Equation with a label and a caption

If an equation has a caption as well as a label, capture a fig element containing the label, caption, and equation.

The Silverchair platform does not currently support display of disp-formula within fig.

From Trevor Hiblar (15 April 2019 email to Mark Dunn): we’d be okay with using //fig/disp-formula and it would import into the database as part of the fig, but in order to display the formula on the sites an update would be needed.

The only content so far seen with equation captions is a US HE book, not currently scheduled for migration to the Silverchair platform. The Silverchair update has therefore not yet been requested (a ttime of writing, 25 April 2019).
