Template:Refname rules


 * Names are case-sensitive
 * Names MUST NOT be purely numeric; rather, they must have semantic value so that they can be more easily distinguished from each other. Prefacing a number with a colon does not add semantic value.
 * Names must be unique—you may not use the same name to define different groups or footnotes
 * Quotation marks are optional if the only characters used are letters,  , digits  , and the symbols.
 * The forbidden printable ASCII characters are.
 * Inclusion of any other characters,, requires that the reference name be enclosed in quotes:.
 * The quote marks must be the standard straight keyboard marks ; curly or other quotes will be parsed as part of the reference name.
 * Quote-enclosed reference names may not include a less-than sign or a double straight quote symbol . These may be escaped with   and , respectively.
 * Please consider keeping reference names simple and restricted to the standard English alphabet and numerals.
 * You may optionally provide reference names even when the reference name is not required. This makes later re-use of the sourced reference easier.
