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