How does MicroStation GeoGraphics round trip elements from Oracle Spatial and keep MicroStation specific element attribute information?
MicroStation GeoGraphics by default relies on feature definitions to faithfully reproduce elements. However, in anticipation of future standards for storing style, we also store this information in XML format for all geometries. In MicroStation GeoGraphics, a query option “Use XML Style” is provided if you wish to override display based on feature code definitions and use XML definitions. Advanced users can utilize the XML data stored by MicroStation GeoGraphics to return elements with attributes intact when using software other than MicroStation GeoGraphics.
