The suffixes listed are prefixed by the current <ReaderKeyword> in a mapping file. By default, the <ReaderKeyword> for the OS VectorMap District reader is OSVECTORMAPDISTRICT.
DATASET
This directive specifies the location for the input OS VectorMap District instance document.

MAP_GEOMETRY_COLUMNS
This directive specifies whether the GML geometric properties should be represented as individual, and possibly multiple, geometry columns in FME feature type definitions.
A geometric column in an FME data feature is represented either as a single named geometry, or, if multiple geometry columns are present, as an aggregate geometry with multiple named geometry components, this aggregate geometry will also have its “Contains Individual Geometries” interpretation flag set.
A new attribute type has also been introduced for specifying the order and/or position of a geometric column in the feature type definition. If an attribute X has its type set to xml_geometry, this attribute X becomes a placeholder in the feature type definition. It is a placeholder because actual data features for the feature type definitions will not have this attribute; instead, the data features will have a geometry named X.

EXPOSED_ATTRS
This directive allows the selection of format attributes to be explicitly added to the reader feature type.
This is similar to exposing format attributes on a reader feature type once it has been generated; however, it is even more powerful because it enables schema-driven applications other than Workbench to access and leverage these attributes as if they were explicitly on the schema as user attributes.
The result of picking a list of attributes is a comma-separated list of attribute names and types that will be added to the schema features. Currently all reader feature types will receive the same set of additional schema attributes for a given instance of the reader.

Not applicable.
While it is possible for FME Objects applications to invoke this directive, the required format is not documented.
This directive is intended for use in our GUI applications (for example, Workbench) only.
