OpenStreetMap (OSM) XML Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
Please see the Writer Overview for details on how the features are converted into OSM elements in the OSM Writer.
Geometry
The geometry features produced by the OSM reader can be identified by the xml_type attribute. The valid values for this attribute are:

xml_point |
Point feature. |
xml_line |
Linear feature. |
xml_area |
Simple polygon, donut, or an aggregate of polygon and donut features. |
No Geometry
xml_type: xml_no_geom
Features with their xml_type attribute set to xml_no_geom do not contain any geometry data.
Points
xml_type: xml_point
Features with their xml_type set to xml_point are single coordinate features or an aggregate of single points.
Lines
xml_type: xml_line
Features with their xml_type set to xml_line are polyline features or an aggregate of polylines.
Areas
xml_type: xml_polygon
Features with their xml_type set to xml_polygon are polygon features which may or may not have interior boundaries, or an aggregate of such polygons.
