-At least one of `readonly`, `get`-visibility, and `set`-visibility must be specified.  If at least one is specified, the others may be omitted.
+The set-visibility modifier (`public(set)`, `protected(set)`, `private(set)`) was added to the modifier ordering, between the general visibility and the `static` modifier.
+
+All modifier keywords MUST be all lower-case. The `public` keyword MAY be omitted when using a set-visibility on a public-read property.
