  - #### right

    Flags: RAM,runtime,AVals:3

    Multiplicity: [0,1]

    Strategy to process values from the right-hand-side object.

  - #### valueExpression

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Expression to process every value (if specified by strategy). The value that the expression returns will be taken. If the expression returns null then the value will be skipped.
