 The following `TabSet` component maintains a set of tabs. The tab set's `Tab` components, which are created later in this section, supply the list items (`<li>...</li>`) for the list (`<ul>...</ul>`).
 
-Child `Tab` components aren't explicitly passed as parameters to the `TabSet`. Instead, the child `Tab` components are part of the child content of the `TabSet`. However, the `TabSet` still needs a reference each `Tab` component so that it can render the headers and the active tab. To enable this coordination without requiring additional code, the `TabSet` component *can provide itself as a cascading value* that is then picked up by the descendent `Tab` components.
