My point remains:  If your items contain a set of PTVs or are
fundamentally based on PTVs, then perhaps the substitution markup
should have a colon in it somewhere.  That's how PmWiki consistently
distinguishes {$Name} from {$:Name}.

We can also update FmtTemplateVars to do things based on PTVs --
i.e., {$$:Name}  would be an immediate template substitution of
the 'Name' PTV for a page.
