Template:Refname rules

Names for footnotes and groups must follow these rules:


 * Names are case sensitive
 * Names may not be a numeric integer
 * 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 require that the name be enclosed in in straight quotes (")
 * Quote enclosed names may not include a less-than sign (<) or a quote symbol (")

It is recommended that names be kept simple and restricted to the standard English alphabet and numerals.
