Works for me...

There is still the question of how to render <<|TrailPage|>> when 
the current page is off-trail. The above implies no trail markup
for off-trail pages. To force visible trails, options include:

    (:trails {$Group}.TrailPage *Main.TrailPage 
        PmWiki.DocumentationIndex:)

where the * indicates make this trail always visible; or

    (:showtrails {$Group}.TrailPage Main.TrailPage 
        PmWiki.DocumentationIndex:)

which makes all trails in the directive visible.

The first is briefer; the second is clearer.
