Some words about current infobxes
I am not pointing at anybody, just noticed a mistake(or was it intentional?) in infobox use.
In this example the |item type -value was changed from "clothing" to "Clothing" and after the change it has lost it's link. On the other "CLothing" is correct since it is the name of the category. However, parameter "|item type" was designed to display link to relative category when used one of the predefined values. If the value is not in the list, it won't appear as a link. Summary: for infobox the value "clothing" was more correct.
List of other predefined values for "|item type": clothing, food, drink, first aid, tool, material, other. The list can be found not only in the source of the infobox template but also in the description of the Template:Infobox/Item or directly from Template:Infobox/Item/doc along with other useful information and all the available parameters.
