Hello Patrick,

it is likely that it is too late for ant 1.8.1, unless the build of Friday does not pass the vote.

The other questions are ? What is the use case for this mapper ? Is it generic enough to be added to ant ?

If it interesting we would need also patches of documentation and unit tests.

Regards,

Antoine
