Category:Articles which need to have coordinate zone specified

This category contains articles that use co or coords incorrectly. There are two common causes for an article to end up in this category. The most common cause is that the editor omits the zone. The template requires three parameters: x coord. The second most common cause is that the editor separates the x and y coordinates with a comma instead of a pipe (|). This causes the zone to be interpreted as the y coordinate.
