How to handle errors with REST? Use SOAP

Steve Loughran, and strong REST supporter, has made an interesting blog post suggesting that REST applications use SOAP faults to handle errors.

I'm doing a couple of presentations on REST and SOAP in the upcoming weeks: on Thursday at Emerging Tech for the Enterprise and then ApacheCon Europe.

The lack of a standard way of reporting errors hadn't really been on my list till now - I had assumed that the richness of the HTTP error codes was enough, so this is a good addition to my list of REST and SOAP issues.
