A Data Type defines extraction logic for a distinct type of data, such as a field value or a table row. Each data type defines one or more
extractors, along with settings which control how the extractor results are transformed into a final result set.
At runtime, a Data Type will execute the following extractors, in the order shown.

can be simplified if scope is limited to a small portion of the document. When an input filter is specified, it is executed against the source.
The Data Type's extractors are then executed on each instance returned by the input filter. |

SubtractionExtractor |

An optional extractor to be used for removing content from output values. If an extractor is specified, it will be executed against each final output value. Any content which matches the extractor will be
removed from the output value. If the resulting output value is empty or contains only whitespace characters, the entire output value
