Hi Susan,
The array for the output positions gives extra information that cannot be
derived from the input positions.
Bert Frees gave the example:
input: "100"
outputPos: [1,2,3]
output: "#ajj"
inputPos: [0,0,1,2]
The first position in outputPos points to the output character at position
1, not zero, so it skips the braille indicator. If this was the result of a
contraction rule (replacement), it would point to position zero.

pass (forward translation only)
I think all you need is what you call inputPos along with the input and
output. I don't think you need outputPos.
inputPos: [0,0,1,2]
The zero-based positions in the inputPos array reference the zero-based
positions in the braille output and the corresponding values in the same
array are the zero-based positions in the print input.
In this example the braille cells at positions zero and one in the braille
output translate the print at position zero; the braille cell at position
two in the braille translates the print at position 1; and the braille cell
at position three translates the print at position two.
