-     *      'Namespace' => array(
-     *          'Directive' => new stdclass(),
-     *      )
-     *  )
-     *
-     * The stdclass may have the following properties:
-     *
-     *  - If isAlias isn't set:
-     *      - type: Integer type of directive, see HTMLPurifier_VarParser for definitions
-     *      - allow_null: If set, this directive allows null values
-     *      - aliases: If set, an associative array of value aliases to real values
-     *      - allowed: If set, a lookup array of allowed (string) values
-     *  - If isAlias is set:
-     *      - namespace: Namespace this directive aliases to
-     *      - name: Directive name this directive aliases to
-     *
-     * In certain degenerate cases, stdclass will actually be an integer. In
-     * that case, the value is equivalent to an stdclass with the type
-     * property set to the integer. If the integer is negative, type is
-     * equal to the absolute value of integer, and allow_null is true.
-     *
-     * This class is friendly with HTMLPurifier_Config. If you need introspection
-     * about the schema, you're better of using the ConfigSchema_Interchange,
-     * which uses more memory but has much richer information.
