# About demo/dita-sample.ditamap

The goal of demo/dita-sample.ditamap is very modest: allow the curious person to see how DITA topics and maps looks styled by XXE. This document is by no mean a DITA tutorial.

If you use XXE to author DITA documents:

- You'll be able to use not only PNG, JPEG and GIF images to illustrate your documents, but also any image format supported by an image toolkit plug-in.

  # The image element contained in this fig element points to an SVG file. (Requires the add-on called "Batik image toolkit plug-in".)

- You'll be able to embed
  MathML
  equations in your topics and, using the MathML tool, to edit these equations without really having to learn MathML.

  # This fig element contains a foreign element itself containing a mml:math element. (Requires the add-on called "MathML support" in order to be able to edit the equations.)

Of course, converting DITA documents making use of the above features to formats such as HTML, PDF, RTF, etc, works fine. You just need to install the following add-ons:

- The add-on called "XSL-FO processor plug-in". Note that due to add-on dependencies, installing this add-on will automatically install the add-on called "Batik image toolkit plug-in".
- The add-on called "MathML support".

Installing add-ons consists in selecting menu item Options Install Add-ons , selecting the desired add-ons, clicking OK and then restarting XXE as instructed by the application.
