Template:UnusedParamName/doc

Description

One of the most prominent examples is the ‎<syntaxhighlight> invoked with {{#tag}} in a template. The short version could like this:

{{#tag: syntaxhighlight<!--
-->|{{{1}}}<!--
-->|{{#if: {{{inline_param|}}}|inline|{{UnusedParamName}}}}=1<!--
-->}}

Here, the ‎<syntaxhighlight> is invoked with a single attribute, which name can resolve to either inline, if a param named inline_param is present, or to {{UnusedParamName}}.
Since inline is an attribute which enables the inline display of the code if it's present, to disable it we need to not pass it as a parameter, which can be done by dynamically generating the attribute name.
In cases, where inline and other similar attributes should not be present, they are instead replaced with {{UnusedParamName}}, which is likely not to be used by target template.

The value of this template (wrapped in code for clarity): @@__UNUSED_PARAM_NAME__@@
