-- A "hash" / table of everything TemplateData takes
-- to ease maintenance.

-- The type is automatically determined if t is omitted.
-- If the type does not match or can't be converted, an error will be thrown!
-- Available types (LUA-Types with exceptions): 
--      InterfaceText, boolean, number, selection, table, string
-- selection*: - requires a selection-string of pipe-separated possibilities to be supplied
-- InterfaceText*: A free-form string (no wikitext) in the content-language of the wiki, or, 
-- an object containing those strings keyed by language code.
