        <h2>SVG output</h2>

        <p>
            At the end of the pipeline, different Serializers can generate different output formats,
            provided they're fed the right data (i.e. the required XML elements and namespaces).
        </p>
        <p>
            Let's generate a simple graph out of of our request parameters. If your have an SVG
            plugin in your browser you can view the result: <a href="../red/request.svg">red/request.svg</a>
            or <a href="../blue/request.svg">blue/request.svg</a>. If you don't have an SVG plugin see
            below for the bitmapped version of the same image.
        </p>

        <h3>Sitemap excerpt</h3>
        <cinclude:include element="xml-code" src="cocoon:/xml-element/pipelines/sitemap.xmap/svgRequest"/>

        <h3>XSL transformation</h3>
        <p>Here we show only the main template wich generates the SVG skeleton</p>
        <cinclude:include element="xml-code" src="cocoon:/xml-element/pipelines/xsl/request-to-svg.xsl/main"/>

        <h3>Typical output</h3>
        <cinclude:include element="xml-code" src="cocoon:/pipelines/red/request.svg"/>

        <h2>Bitmapped output</h2>

        <p>
            Post-processing the SVG output allows us to generate JPEG
            (<a href="../cyan/request.jpeg">cyan/request.jpeg</a>)
            or PNG
            (<a href="../black/request.png">black/request.png</a>)
            images, simply by configuring
            a different serializer at the end of the pipeline.
        </p>

        <h3>Sitemap excerpts</h3>
        <p>
            Note the use of the <em>cocoon:/</em> protocol to re-use the previous pipeline as input: when a request
            to <em>blue/request.png</em> is received, the output of the <em>blue/request.svg</em> is used
            as the input of the first pipeline shown below.
        </p>
        <cinclude:include element="xml-code" src="cocoon:/xml-element/pipelines/sitemap.xmap/pngRequest"/>
        <cinclude:include element="xml-code" src="cocoon:/xml-element/pipelines/sitemap.xmap/jpegRequest"/>
