|This is a documentation subpage for Template:! (see that page for the template itself).
It contains usage information, categories, and other content that are not part of the original template page.
This is an auxiliary template allowing to encode "
|" within template parameters. It is necessary if the character is used in wiki table syntax. In other cases it is better to use "
This template cannot be used for putting the character as text in a wiki table; in that case, again, "
|" can be used.
Note that no special template is needed for "
!" (exclamation mark).
This is a high risk template, and it cannot be substituted.
