img-eqnref

Description

Returns a unique reference to an equation. If the element does not have one of MEQUATION or MEQNARRAY in its ancestry (for example because it is an M element), then we won't need to refer to this label. It must, however, be generated and be unique.

Argument list
nd = node-list (Given), optional

A singleton node-list containing the element which is to be referred to.

Return value

Type: string

String usable as an ID attribute value.
