This is helpful when some codec have format restrictions and e.g. don't support a 32-bit format. In that case, the copier output formats mirror that restriction in the topology file. An alternate solution was suggested earlier using a dedicated topology token. When specified, the token would be used to fix-up the dailink. The main reason why this solution was chosen is that there is a risk of a disconnect between token definition and copier format. With a single piece of information as suggested in this patch, there are fewer risks of a bad configuration.
