   You can adjust the depth of section levels that are displayed in the PDF outline independent of the TOC level depth with the `outlinelevels` document attribute.
   By default, `outlinelevels` is set to the same value as `toclevels` and all the included levels are fully expanded.
  
positive.code: The outline can also be deactivated with the `outline` attribute.
  
  [#title]
  == outline-title
  
  By default, the document title is displayed as the title of the PDF outline.
  You can customize the outline title using the `outline-title` document attribute.
  
negative.code: ----
  <.> Directly after the first integer, enter a colon (`:`), and then a second integer.
  
  You can also override the `outlinelevels` document attribute for a specific section and its children by setting `outlinelevels` on the section's parent.

  <.> The `outlinelevels` document attribute is set to `1`.
  The resulting PDF outline will list the part titles (if present and the doctype is `book`) and level 1 (`==`) section titles.
  <.> Set `outlinelevels` on the parent section title that will already be listed in the PDF outline due to the global `outlinelevels` value.
  Assign the `outlinelevels` on the section title the numeric value of the next section level you want to be inserted into the PDF outline.
  <.> This section title (and any of its children) will be listed in the PDF outline because `[outlinelevels=2]` was assigned to its parent section title.
