SDO_GEOMETRY
The geometry type of an XFM feature is determined dynamically during registration in Bentley Geospatial Administrator. This is done by looking at the Oracle Spatial spatial index defined for the geometry table.
For example, a point spatial index: CREATE INDEX hnod_tugs_idx ON hnod_tugs(Geometry) INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS ('layer_gtype=point');
