Flash and XML Website with CMS (via XML)

We're planning to do a full-browser portfolio website with Flash based on the Typolight CMS: [login to view URL] Instead of HTML pages we would generate XML files with the CMS which contain the navigation and the content etc. The website then works with deep linking. The website should have similar features as [login to view URL] The website has to be SEO-optimized. Alternatively, we need to do a XHTML version of the website. The Flash website contains basically the following page types: - Content pages (with images) and floating text (left, right) - Fullbrowser gallery (big images) with navigation. These galleries can have different styles (background color etc.) - Event-list - Contact forms In the XML file we will indicate the design of the pages etc. A XML file could look like this: <template>content page</template> <menu> <link href="/#/home">home</link> <linkset> <main href="/#/about">about</main> <submenu> <link href="/#/about/story">story</link> <link href="/#/about/story">story</link> </submenu> </linkset> </menu> <news> <item date="Oct 20, 2009" title="First news">some news</item> </news> <content> <gallery name="Landscapes" description="This is a description"> <image src="test.jpg" title="Nice landscape" additional="Buy now"></image> </gallery> </content> </page>
