The Graphical Data Mapper does apply strong type checking against the schema models for the input and output of the transforms.

If the model defines elements as optional or nillable, they will satisfy the type checking but may be not present during execution.

It appears that what you want to do here is reuse a submap that is designed for transforming a set of "N" elements in a case where you only have "N-2" elements in your input data.

The type checking will prohibit you from providing "dummy inputs".

Perhaps the solution you need to look to is to layer your submaps, so that you have a sumap that takes "N" inputs and then calls a nested submap taking the "N-2" inputs, which may also be used directly.
