This is an auxiliary template allowing to encode "|"
within template parameters. It is unnecessary to get a
"|" in these cases, better use "|"
for this purpose. However the "|" delimiter for a
Wiki table has to be escaped by a template if it's used
within a template, see also WP:QIF.
Note that there's no such problem with "!" (exclamation mark), it
only affects "|" (vertical bar) in conjunction
with the m:Help:Parameter_default mechanism within tables.
For obvious reasons this is a high risk template, and it cannot be substituted.
