Not necessarily. XML is structured text. So is the template IR language
that is the subject of this long discussion. This, for example:

  [orderedlist
    [One]
    [Two]
    [Three
      [itemizedlist
        [Three.a]
        [Three.b]
        [Three.c]
      ]
    ]
    [Four]
  ]

is a structured tree, but it is *still* textual. The wiki preprocessor
can be a lexical processor that generates the code above from this
wiki text:

  # One
  # Two
  # Three
      * Three.a
      * Three.b
      * Three.c
  # Four

So, in a sense, the wiki parser should know a bit about
(a subset of) the IR language, enough to generate what it
needs to deal with.
