*** type attribute is an enumerated attribute indicating the kind of menu being declared. The attribute has three states. The context keyword maps to the context menu state, in which the element is declaring a context menu. The toolbar keyword maps to the toolbar state, in which the element is declaring a toolbar. The attribute may also be omitted. The missing value default is the ... state, which indicates that the element is merely a list of commands that is neither declaring a context menu nor defining a toolbar.

... consists of a week-year number and a week number representing a seven-day period starting on a Monday. Each week-year in this calendaring system has either 52 or 53 such seven-day periods, as defined below. The seven-day period starting on the Gregorian date Monday December 29th 1969 (1969-12-29) is defined as week number 1 in week-year 1970. Consecutive weeks are numbered sequentially. The week before the number 1 week in a week-year is the last week in the previous week-year, and vice versa. [GREGORIAN]
