/**
 * Generate an HTML <code>&lt;frame&gt;</code> tag with similar capabilities as
 * those the <code>&lt;html:link&gt;</code> tag provides for hyperlink
 * elements.  The <code>src</code> element is rendered using the same technique
 * that {@link org.apache.struts.taglib.html.LinkTag LinkTag} uses to render
 * the <code>href</code> attribute of a hyperlink.  Additionally, the HTML 4.0
 * frame tag attributes <code>noresize</code>, <code>scrolling</code>,
 * <code>marginheight</code>, <code>marginwidth</code>,
 * <code>frameborder</code>, and <code>longdesc</code> are supported.  The
 * frame <code>name</code> attribute is rendered based on the
 * <code>frameName</code> property.
 *<p>
 * Note that the value of <code>longdesc</code> is intended to be a URI, but
 * currently no rewriting is supported.  The attribute is set directly from
 * the property value.
 *<p>
 * This class is a subclass of the class
 * <code>org.apache.struts.taglib.html.FrameTag</code> which provides most of
 * the described functionality.  This subclass allows all attribute values to
 * be specified as expressions utilizing the JavaServer Pages Standard Library
 * expression language.
