The problematic value of DayOfWeek is
http://purl.org/goodrelations/v1#PublicHolidays , which is-not-a day of the
week, but is a completely reasonable specifier for picking out a class of
days to which an opening hours specification should apply (thus +1 on your
openingHoursSpecification recommendations ).
[ It is possible to define a subclass of schema:DayOfWeek that included
only the seven elements that occur every week (for a fixed calendar
system); however, that new class would seem to more closely match the
general intuition of what a day of the week might be. ]
