Thank you, thank you, thank you!

That is exactly what I needed. I hadn't considered "choice" as a solution to
this problem because I thought that it only allowed one of the listed
elements. In 3.7 of the Structures draft it states

(choice) corresponded to exactly one of the specified {particles};

and the Primer has a similar description, so I hadn't pursued it further.

Thanks,
Glen Albert
