/**
* TStyleSheet class.
*
+ * TStyleSheet represents the link to a stylesheet file and/or a piece of
+ * stylesheet code. To specify the link to a CSS file, set {@link setStyleSheetUrl StyleSheetUrl}.
+ * The child rendering result of TStyleSheet is treated as CSS code and
+ * is rendered within an appropriate style HTML element.
+ * Therefore, if the child content is not empty, you should place the TStyleSheet
+ * control in the head section of your page to conform to the HTML standard.
+ * If only CSS file URL is specified, you may place the control anywhere on your page
+ * and the style element will be rendered in the right position.
