Generally agreed, but would suggest a slightly different set of concerns separated. instead of separation of content, layout, and styling, I would suggest a separation of data, structure, and styling. Data + structure gives you content, structure plus styling gives you layout. So in this idea you might have RDF as data, an HTML template as structure, and CSS as styling. The browser would generate the HTML from the template and the RDF, and the CSS would then be used to lay it out and style it.
