Changes

The template {{tl|as of}} is used to mark potentially dated statements, and will add an article to the appropriate [[WP:HIDDENCAT|hidden]] sub-category of [[:Category:Articles containing potentially dated statements]]. This allows editors to catalogue statements that may become dated over time. The date used for a given statement should be the current date (for currently valid statements) or the date on which the cited reference was produced (for example, when using census data). It also includes the [[WP:ISO 8601|ISO 8601]] format needed by [[hAtom]] (<code>class="updated"</code>) and [[hCalendar]] (<code>class="dtstart"</code>) [[microformat]]s through use of the {{tl|start date}} template. Unlike the {{tl|update after}} template, {{tl|as of}} does not require the editor to give a full date. This template should '''not''' be [[Wikipedia:Substitution|substituted]].
