If the Apply Transformation Scenario button from the Transformation toolbar is pressed, currently there is no scenario associated with the edited document and the edited document contains a xml-stylesheet processing instruction referring to a XSLT stylesheet (commonly used for display in Internet browsers), then Oxygen will prompt the user and offer the option to associate the document with a default scenario. The default scenario contains in the XSL URL field the URL from the href attribute of the processing instruction. This scenario will have the Use xml-stylesheet declaration checkbox set by default, will use Saxon as transformation engine, will perform no FO processing and will store the result in a file with the same URL as the edited document except the extension which will be changed to html. The name and path will be preserved because the output file name is specified with the help of two editor variables: ${cfd} and ${cfn}.
Oxygen comes with preconfigured built-in scenarios for usual transformations that enable the user to obtain quickly the desired output: associate one of the built-in scenarios with the current edited document and then apply the scenario with just one click.
