Wiki Template Documentation

Segregating documentation to a subpage means that updates to the documentation don't cause large numbers of pointless template updates across the wiki, and the template itself can be protected if necessary (without protecting the documentation). That is, each time a change is made to a template, all pages that use that template are updated, which can be significant for widely used templates. Similarly, when changes are needed to a widely used template, experiment first on Sandbox so only a single change will be needed to the template itself.
 * Documentation for templates should be stored on a subpage of the format "Template Name/Doc".
 * Refer to the documentation by placing  at the bottom of the template page.
 * Under "Syntax" include examples that are copy/paste friendly using the pre tag of the template syntax.
 * Under "Usage" include information about where the template should be used and any special parameter information. If appropriate, provide examples to make usage as clear as possible.
