IMHO, it could be also nice to have individual pages for each farmer,
defining the data as a set of PageTextVariables.

This would enable all the (:pagelist ...:) feature to handle the list
itself, and the rendering could be done with a dedicated
"pagelist-formater" function responsible to "extract" some
PageTextVariables definitions from page fragments, and to render them
as "wiki blocks" (ie. the recipeinfo block of some Cookbook pages) or
as a xml data set according to the $action context (browse or xml).
