$node: The `co` element to create a callout label for.
This template creates a label for a callout, taking a `co` element as the
$node parameter. The label is numbered according to the position of the `co`
element in the document. To create the corresponding label for a `callout`
element, locate the corresponding `co` element and call this template on it.
