This is a template for the XML format used for syntax highlight descriptions
for the Kate text editor (http://kate.kde.org), which is part of the KDE
desktop environment (http://www.kde.org).

Use it as the base for your own syntax files.

Look at language.dtd for some documentation of the allowed elements and their attributes.
There is also a description of how to validate your syntax file.
