|| This template is used on 57000+ pages.
To avoid large-scale disruption and unnecessary server load, any changes should first be tested in this template's /sandbox or /testcases subpage, or in your own user space. The tested changes can then be added in one single edit to this template. Please consider discussing any changes on the talk page before implementing them.
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 "
||". However the "
||" delimiter for a Wiki table has to be escaped by a template if it is used within a template.
There is no such problem with "
!!" (exclamation marks). This problem only affects "
||" (vertical bars) in conjunction with the m:Help:Parameter default mechanism within tables.
This template cannot be substituted.
