I noticed another bug in the RNG. The collected RNG is missing a '?' after atomIcon:
> atomSourceFeed = > element atom:source-feed { > atomCommonAttributes, > ( atomTitle > & atomUpdated > & atomLink+ > & atomIcon should be: > atomSourceFeed = > element atom:source-feed { > atomCommonAttributes, > ( atomTitle > & atomUpdated > & atomLink+ > & atomIcon? -- Dave
