* It Allows any possible attribute configuration in its inputs and in
* its output, but it performs faster when prototype configuration of
* the data is specified using SetPrototypes(...), in certain
* situations:
* <ul>
* <li> When all the inputs and the outputs have a common attirbute
* (not the BPF), and the same scale.
* <li> When one of the inputs has just a BPF attribute, and both the
* other input and the output have a common (non-BPF) attribute
* with the same scale in both objects.
* <li> In other cases, at least a vector conversion will be executed
* in one of the involved processing data objects. In some bad
* situations two conversions might be needed.
