This is required because "tristate" is not officially supported as an
attribute type. An equivalent attribute type is an in with a constrained
set of values, namely [-1, 0, 1]. Unfortunately, tristate accepts
multiple types, integers, booleans and strings ("auto"). As a result, this
method normalizes the inputs to an integer.
This method needs to be applied to attributes that were formally tristate
to normalize the inputs.
