I'm not quite sure what the goal is either. Is it to replace the current theme/layout mechanism in Portal? If yes, the layout engine should be flexible to accommodate people's need with minimum development. Ideally, the generated markup would be semantically correct (not only, would it pass HTML validation but the elements used to structure the markup would actually make sense based on their intent as opposed to how they are rendered by user agents) and not rely on tables for the layout. This would make it easier for designers to just change the layout by changing the CSS. The markup should also support accessibility needs as much as feasible.
