I'm only concerned with validating issue dates here. In DSpace they are generally always YYYY, YYY-MM, or YYYY-MM-DD (though in theory they could be any valid ISO8601 format). This also checks for cases where the date is missing and where the metadata has specified multiple dates like "1990||1991", as this is valid, but there is no practical value for it in our system.
