/**
 * Represents a <code>SetTabIndex</code> tag in a SWF file.
 * <p>
 * Flash Player maintains a concept of tab order of the interactive and textual
 * objects displayed. Tab order is used both for actual tabbing and, in SWF 6
 * and later, to determine the order in which objects are exposed to
 * accessibility aids (such as screen readers). The SWF 7 SetTabIndex tag sets
 * the index of an object within the tab order.
 * <p>
 * If no character is currently placed at the specified depth, this tag is
 * ignored.
 * <p>
 * You can also use using the ActionScript tabIndex property to establish tab
 * ordering, but this does not provide a way to set a tab index for a static
 * text object, because the player does not provide a scripting reflection of
 * static text objects. Fortunately, this is not a problem for the purpose of
 * tabbing, because static text objects are never actually tab stops. However,
 * this is a problem for the purpose of accessibility ordering, because static
 * text objects are exposed to accessibility aids. When generating SWF content
 * that is intended to be accessible and contains static text objects, the
 * SetTabIndex tag is more useful than the tabIndex property.
