 This is a documentation subpage for Template:!!. It contains usage information, categories, interlanguage links 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.
Notes
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.
