+ * This class is for runtime permissions. A RuntimePermission
+ * contains a name (also referred to as a "target name") but
+ * no actions list; you either have the named permission
+ * or you don't.
+ *
+ * <P>
+ * The target name is the name of the runtime permission (see below). The
+ * naming convention follows the  hierarchical property naming convention.
+ * Also, an asterisk
+ * may appear at the end of the name, following a ".", or by itself, to
+ * signify a wildcard match. For example: "loadLibrary.*" or "*" is valid,
+ * "*loadLibrary" or "a*b" is not valid.
+ * <P>
+ * The following table lists all the possible RuntimePermission target names,
+ * and for each provides a description of what the permission allows
+ * and a discussion of the risks of granting code the permission.
+ * <P>
