1) Test basic template handling for the following:
  <pdftemplate/>

  ------

  <pdftemplate pagesize="Letter">
    <pagedef/>
  </pdftemplate>

  ------

  <pdftemplate pagesize="Letter">
    <pagedef>
      <font face="Times-Roman" h="8">
        <row>
          <textbox w="100%" text="Hello, World!">
        </row>
      </font>
    </pagedef>
  </pdftemplate>

2) Build templates to test the following nodes by themselves:
    * Always
      - In the middle of the page
    * Bookmark
    * Circle
    * Conditional
      - if-true
      - if-false
      - if-else-true
      - if-else-false
    * Footer
    * Header
    * HorizontalRule
    * Image
    * Line
    * Loop
      - Both Y and X directions
    * PageBreak
    * Scope
    * Section
    * Var
    * Weblink

3) The following nodes need to be tested together:
    * Loop and any combination of the following inside:
        Always (Does this always appear at the same spot in the page?)
        Footer (where is the loop pagebreaking?)
        Header (where is the loop starting?)
        PageBreak
        PageDef
        Section
        Textbox (enough to make the loop run over the page)
    * Nested loops and the nodes above
        Outer in Y and Inner in X (and vice-versa)
    * Pagebreak within a:
        Always/Footer/Header
        Section
        Conditional
    * Always within a Always/Footer/Header
    * Footer within a Header (and vice-versa)

4) Handling of context and scoping
    * Does scoping work?
    * Will the construct <row h="+2"> work? What about -2, *2, and /2?
    * Does overriding the value in an inner node work?
    * Do units work?
      - inches
      - centimeters
      - points
      - decimal values
      - negative values
    * Do percentages work correctly?
      - negative percentages
      - percentages > 100%

5) Variables
    * Do variables work using the <var> tag?
    * Do variables work using the "$foo" syntax?
    * Do <textbox> and <image> correctly use attributes over contained TextObjects?
    * Do system-defined variables work correctly?
      - __PAGE__
      - __LAST_PAGE__
      - __PAGEDEF_PAGE__
      - Loop: __FIRST__
      - Loop: __LAST__
      - Loop: __INNER__
      - Loop: __ODD__
    * Do inner loops correctly override the outer-loop's variables?
      - Is the outer's value used when the inner doesn't specify?
    * Does DIE_ON_NO_PARAM work correctly?
