Template:!!/docEdit This Page
From FamilySearch Wiki
| This is a documentation subpage for Template:!! (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.
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 mw:Help:Parameter default mechanism within tables.
This template cannot be substituted.
