Yeah. The way it's written fails to show, except via formatting, that IMMUTABLE/STABLE/VOLATILE are mutually exclusive;
It seems the STRICT -ness line needs brackets too then.
Also, back to volatility, volatile is the default option though due to alphabetical order it is shown last with no indication it is the default. Do we have an existing convention in the syntax section to indicate defaults, either with emphasis, placement, or even an annotation like "*"?
