Hi Peter, Your point is well taken -- we've been working through the syntax to see what the implications are for our own tools, and expect to have a better idea later this week. There is clearly information encoded in the diagrams that is not present in the written syntax, but we're still trying to understand the impact. I hope to provide more feedback once we've completed the analysis. Thanks, Elisa Peter F.
