→General: Fixed wikilink. The wililink behind "Substituting" was pointing to "Substitutionary atonement". Don't know if that was vandalism or just an accident using the article picker. It was really funny, though; I did not expect that at all. Tags: Mobile edit Mobile web edit |

Line 58 ⟶ 56:
The value of a parameter can be an [[empty string]], such as when the pipe (<code>|</code>) or equals sign is followed immediately by the next pipe or the closing braces. For example, <code><nowiki>{{Template name|1=|2=test}}</nowiki></code> produces the same output as <code><nowiki>{{Template name||2=test}}</nowiki></code>. This is different from not specifying the parameter at all, which results in a default value, although templates are often coded so as to behave the same in both cases.
If a template call specifies a parameter which is not defined in the template, it has no effect. Editors sometime specify a parameter they know is not defined in the template
