By the time the markup is being processed, it's too late to do anything
useful with $DefaultPageTextFmt.  $DefaultPageTextFmt determines what
text (markup) to use if a page doesn't exist -- thus it has to be
handled _before_ any markup processing takes place.

What you may want to do instead is:

    SDV($DefaultPageTextFmt, 
      '(:include {$Group}.pmPageNotFound $[{$SiteGroup}.PageNotFound:)');

This uses the pmPageNotFound page of the current group if it exists,
falling back to Site.PageNotFound if it doesn't.
