A form processing application may require (or prefer) use of a non Accusoft component. These components can still be integrated with FormDirector.
Majority of data in FormDirector is stored as strings. So, as long as a descriptive string can be generated to describe the operation to be performed by the component (operation control parameters), then the operation can be represented by a FormDirector DataItem object.
The DataItem Type string must start with the underscore character ("_"), in order for the type string to be considered valid by FormDirector.
