|---|
|
Most of the category-by-year header templates are designed to be used on pages where the year is part of the page title. In nearly all cases, the year does not need to be supplied as a parameter, because it can be grabbed from the title using . If all uses of a template are on pages which do have a year in the title which matches the year parameters, then the by-year parameters are redundant, and the template can be rewritten to remove them. This system tracks the exceptions, if any. |
