/**
* An annotation indicating the possible values for a String type. The annotation's arguments are
* Java regular expressions. If an expression's type has this annotation, then at run time, the
* expression evaluates to a string that matches none of the regular expressions. Matching is via
* the java.lang.String#matches
* method, which matches against the entire string (it does not look for a match against a
* substring).
