| /** |
| * This Layout module allows Velocity XML templates to be used as layouts. |
| * <br><br> |
| * Once the (XML) screen and navigation templates have been inserted into |
| * the layout template the result is transformed with a XSL stylesheet. |
| * The stylesheet (with the same name than the screen template) is loaded |
| * and executed by the XSLT service, so it is important that you correctly |
| * set up your XSLT service. If the named stylsheet does not exist the |
| * default.xsl stylesheet is executed. If default.xsl does not exist |
| * the XML is merely echoed. |
| * <br><br> |
| * Since dynamic content is supposed to be primarily located in |
| * screens and navigations there should be relatively few reasons to |
| * subclass this Layout. |
