Step 4 - Referencing Styles And CSS
The <param> with the name "Styles" points to the location of the XML document that contains the styles. The <param> with the name "CSS" points to the location of a CSS document. Use an absolute URL when pointing to these files. For example:
<param name="Styles" value="http://myserver/styles.xml" /><param name="CSS" value="http://myserver/format.css" />
