     * The naming convention textMatrixABCDEF refers to in which packages and

     * defined). If defined, a slot is always given the same value.
     *
     * SLOT  PACKAGE           CONFIGURATION  VALUE
     * A     target package    (default)      100
     * B     target package    -sv            200
     * C     OverlayAppFirst   (default)      300
     * D     OverlayAppFirst   -sv            400
     * E     OverlayAppSecond  (default)      500
     * F     OverlayAppSecond  -sv            600
     *
     * Example: in testMatrix101110, the base package defines the
     * R.integer.matrix101110 resource for the default configuration (value
     * 100), OverlayAppFirst defines it for both default and Swedish
     * configurations (values 300 and 400, respectively), and OverlayAppSecond
     * defines it for the default configuration (value 500). If both overlays
     * are loaded, the expected value after setting the language to Swedish is
