lov can be either a list of values enclosed in brackets (each value must be within single quotes and separated by commas) or the name of a class and object separated by a backslash and within single quotes.
MONO means that the prompt accepts only one value. MULTI means that the prompt can accept several values.
FREE refers to free input as opposed to CONSTRAINED, which means that the end user must choose a value suggested by the prompt.
