The driving problem in reverse

My wife had never driven but as she was coming to Spain I thought it might be a good idea if she had a 'non professional' licence. We made the applications, stood in line, paid the fees and she got her licence and International licence (that is NOT a driving licence but a translation of the licence the person holds, so when using it the person MUST have their actual driving licence with them. This applies worldwide). We arrived in Spain and found that we could not exchange the DL from Phil to a Spanish Licence, even through the way they drive here is not far removed from the Phil way ! We had heard that there was an agreement in the pipeline that DLs could be changed, but so far it cannot be done.
