Template:Refname rules


 * Names are case-sensitive
 * Names may not be purely numeric
 * Names must be unique—you cannot use the same name to define different groups or footnotes
 * Quotes are optional if the only characters used are letters A–Z, a–z, digits 0–9, and the symbols
 * Inclusion of any other characters, including spaces, requires that the 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 names may not include a less-than sign or a double straight quote symbol
 * Please consider keeping names simple and restricted to the standard English alphabet and numerals.
 * (You may optionally provide names even when the name is not required.)
