But isn't the schemas distinct enough to always recognize the correct version ? Note: if we can't recognize the version i'm probably fine by falling back to 3.2 by default. btw. why is hard to set a specific version as the default ? Is it hardcoded to take the latest version as default or ? Are you telling me the richfaces team does not update their TLD's ? I thought the CDK where supposed to make that "easy" ? I've cc'ed in Sergey S. to get his opinion on how we should go about supporting updates to richfaces if the libraries does not maintain their schema version id's..? ? /max
