> The approach that [PmWiki](http://www.pmwiki.org) takes is that it enables the optional auto-creation of (empty) pages which match a particular "group" (set of sub-pages); thus one could set all the "tags/*" pages to be auto-created, creating a new tags/foo page the first time the \[[!tag foo]] directive is used. See [[todo/auto-create_tag_pages_according_to_a_template]] for more discussion on this idea.
