32 * DATE_VALUE := {Size=1:35}
33 * [ <DATE> | <DATE_PERIOD> | <DATE_RANGE>| <DATE_APPROXIMATED> | INT <DATE> (<DATE_PHRASE>) | (<DATE_PHRASE>) ]
34 * The DATE_VALUE represents the date of an activity, attribute, or event where:
35 * INT = Interpreted from knowledge about the associated date phrase included in parentheses.
36 * An acceptable alternative to the date phrase choice is to use one of the other choices such as
37 * <DATE_APPROXIMATED> choice as the DATE line value and then include the date phrase value as a
38 * NOTE value subordinate to the DATE line tag.
39 * The date value can take on the date form of just a date, an approximated date, between a date
40 * and another date, and from one date to another date. The preferred form of showing date
41 * imprecision, is to show, for example, MAY 1890 rather than ABT 12 MAY 1890. This is because
42 * limits have not been assigned to the precision of the prefixes such as ABT or EST.
