Note
1=<nowiki> some text </nowiki>
. Occationally, parts of literal displays may confuse the wiki parser. The <nowiki>...</nowiki>
block protects against that. Also if something like n= appears in the literal body, the template parser may get confused. The initial 1=
protects against that. Otherwise this markup has no effect. In short: it can't hurt, and it protects against the possibility of some nasty side effects.
