Idempotent Capability – new pattern description published

A new and improved description of the Idempotent Capability pattern has just been published @ soapatterns.org. The pattern explains why idempotency is important as well as why and how a non-idempotent capability can be transformed into an idempotent capability.

Many thanks to my co-contributor Cesare Pautasso as well as rewievers Radovan Janecek, Ian Robinson and Nicolai Josuttis.
