On reflection, it's better for the page toc recipe to be simple and 
consistent in treating idNames:

- !!([[##idName]] or ##idName) produces a visible anchor (§ or �)

- !!([[#idName]] or #idName) produces a standard anchor, '' for a duplicate

In the latter case, an author can see any duplicates with (:toc 
anchors=visible:) if desired.
