Depends on the RFC. Some WGs run interoperability tests, and those results may be available publicly (although, in at least some cases, they're kept secret, so that engineers can come do their testing without marketing getting worried). Or there may be a test suite publicly available somewhere. Failing that, you're on your own. If it's a widely implemented RFC, you may be able to test it against other implementations. /=================================================================\ |John Stracke |Principal Engineer | |jstracke@incentivesystems.com |Incentive Systems, Inc. | |http://www.incentivesystems.com |My opinions are my own. | |=================================================================| |Among animals, it's eat or be eaten.
