-/**
- * THtmlWriter class
- *
- * THtmlWriter is a writer that renders valid XHTML outputs.
- * It provides functions to render tags, their attributes and stylesheet fields.
- * Attribute and stylesheet values will be automatically HTML-encoded if
- * they require so. For example, the 'value' attribute in an input tag
- * will be encoded.
- *
- * A common usage of THtmlWriter is as the following sequence:
- * <code>
- *  $writer->addAttribute($name1,$value1);
- *  $writer->addAttribute($name2,$value2);
- *  $writer->renderBeginTag($tagName);
- *  // ... render contents enclosed within the tag here
- *  $writer->renderEndTag();
- * </code>
- * Make sure each invocation of {@link renderBeginTag} is accompanied with
- * a {@link renderEndTag} and they are properly nested, like nesting
- * tags in HTML and XHTML.
