Template:!/doc

<Back

This is an auxiliary template allowing one to encode " " within template parameters. It is not necessary to use a " " in these cases; it is better use " " for this purpose. However the " " delimiter for a Wiki table has to be escaped by a template if it is used within a template.

Note that there is no such problem with " " (exclamation point); it only affects " " (vertical bar) in conjunction with the parameter default mechanism within tables.
