I don't think it's minor. Evidence to show it is would be good. One way would be to add a WG note (highlighted box) to the Turtle spec as it is published as WD and in LC to make sure the change is noticed. For people with deployed queries, a software upgrade will now either silently change the meaning of a query (only occurs for BGP trailing 18.) or creates a syntax error in otherwise working systems (the case of "18. ."). That's a big deal for them and their software suppliers. It's because of the success that these things become significant. Establishing a message somehow that further changes to existing systems would be good. > Overall that's a change for the better, I think. > > Best, Richard Andy
