This is an auxiliary template that allows one to encode "||" (two pipes or vertical bars) within template parameters. If it is unnecessary to get a "||", it is better to use "&#124;&#124;". However the "||" delimiter for a Wiki table has to be escaped by a template if it is used within a template.

Notes

There is usually no such problem with "!!" (exclamation marks). This problem only affects "||" (vertical bars) in conjunction with the m:Help:Parameter default mechanism within tables. However, in table rows starting with "!" there can be problems with "!!" being interpreted as a cell separator. Try replacing it with "&#33;&#33;".

This template cannot be substituted.
