Because of the way the dgn file is structured it would be hard to represent the DGN layers as OGR layers efficiently. Also, since all features have the same schema there was relatively little value in keeping them as distinct layers. > 2) Does anybody know about an example of conversion from DGN to SVG? > I think MapServer has some sort of SVG support and given that MapServer has at least some degree of "autostyling" available from OGR DGN it might capture some of the look and feel of the original DGN. I doubt this is a well trod route.
