If valueFrom is a constant string value, use this as the value and
apply the binding rules above.
If valueFrom is an expression, evaluate the expression to yield the
actual value to use to build the command line and apply the binding
rules above. If the inputBinding is associated with an input
parameter, the value of self in the expression will be the value of
the input parameter. Input parameter defaults (as specified by the
InputParameter.default field) must be applied before evaluating the
expression.
When a binding is part of the CommandLineTool.arguments field,
the valueFrom field is required.
