attribute, format

Format attributes are internal attributes usually that carry extra information specific to a format. They may be carried from reader to writer if the format is unchanged, and many can be modified or applied using an appropriate styler transformer such as the MapInfoStyler or DWGStyler (and are then carried to the writer).

They are prefixed with the format abbreviation, for example igds_level or autocad_color.

These attributes are generally not shown by default, but may be exposed.

More rarely, these are used across different formats.
