<!--
This file describes the XML format used for syntax highlight
descriptions for the GtkSourceView 1.x library.
.lang files are XML files which describe how to highlight syntax;
this RNG is used for validation purposes.
.lang files should be located in $PREFIX/gtksourceview-1.0/language-specs/,
or in ~./gnome2/gtksourceview-1.0/language-specs/
To check if a .lang file is valid, run
$ xmllint FILENAME - -relaxng language.rng
If you create a new .lang file or modify an existing one, please note
that it will be (re)loaded by the application only after it is
restarted.

Attributes that are of type boolean allow the following values:
- 'true', 'TRUE' and '1' all meaning true
- 'false', FALSE' and '0' all meaning false
