Specifying a List of Values

To specify two or more values for an attribute, use a comma (,) to separate the values. A range of values is allowed as part of a list. Wildcards and intervals, however, are not allowed.

Duplicates within a list are ignored.

The following expression sets the day of the week to Tuesday and Thursday:

dayOfWeek="Tue, Thu"

The following expression represents 4:00 a.m., every hour from 9:00 a.m. to 5:00 p.m. using a range, and 10:00 p.m.:

hour="4,9–17,22"
