SDV() is a Very Clever PmWiki Core Function (vcpcf) and means "set default 
value" (if none is set). In a recipe, if a user has previously defined a 
variable, the recipe will not change it. This function is usefull for recipe 
authors; recipe users often need to force a value in config.php, and will use 
a direct declaration like $MyVar = 2; instead of SDV().

See http://pmwiki.org/wiki/Cookbook/Functions#SDV for more information.
