Here is a first cut at a patch.  There is one slight deviation from the 
original spec:

The attached patch returns empty mappings for these cases.  I can easily
add the error checks, but in what cases is it useful to know *exactly*
why a mapping could not be created?  Having an empty mapping for all 
invalid cases is simpler and seems more robust.
