    That's what I was looking for.

    I did not see this documented in the Cayenne User's Manual. For
    example, it's not listed in the "Logical Conditions" section of the
    start of chapter 10, which I incorrectly assumed was the exhaustive
    list of expression types.

    Thank you for your help, Andrus and Mike.
