In LaTeX, it is possible to use commands such as \index{foo} and \index{foo|bar} to add terms to a remissive index (usually placed at the end of the book):

Such a feature would also be useful when creating books on Wikibooks.

For example, one could use a new {{#index:foo|bar}} parser function to get a similar functionality.

Alternatively, there could be a {{#pagenumber: some page title}} which, in the PDF file, would output the number of the page where "some page title" starts, or something like that. An editor could then create the index page manually, using a wikitable.
