The showDetailItem component is used inside of a showOne component to contain a group of children. It is identified visually by the the text attribute value and lays out its children. When inside of a parent showOne, "disclosed" and "rendered" mean different things: if "rendered" is false, it means that this item and its contents are not available at all to the user, while if "disclosed" is false, it means that the contents of the item are not currently visible, but may be made visible by the user. It is generally used inside of a showOne component, but may be used on its own, in which case "disclosed" functions equivalently to "rendered", and the "text" attribute is ignored.
