Template:Internationalization template doc

The template automatically sets the following categories:

• Category:Language templates with no text displayed (if parameter #1 is empty)

The template is intended to be used in the following namespaces: all namespaces

The template is intended to be used by the following user groups: all users

Relies on:

• {{Description}}

• Existing "1=" shall not be removed, even if it is not necessary, see Special:Diff/592488152#removing_1=.
• when no free "="-sign occurs in the text the "1=" is obsolete. Not-free equal signs (inside of template transclusions) don't count.
• without the "1=" but with one or more equal signs, no parameter #1 can be detected, and the error "parameter #1 is empty" is categorized.
• As another error, a superflous pipe "|" character converts it to the contrary:

• while e.g. {{en | some text | }} will be understood,
• {{en |1=some text | }} causes the same error "parameter #1 is empty".

When a parameter is required the template documentation expresses it with a line in the table, which left column shows the parameter name, then a textual description for the parameter value, and right the code (in this case) "required".

• A named parameter needs to be specified by name=, which may as well be an alias,
• a positional parameter is specified either by its position or by the positional number (e.g. 1=, 2=, 3=...). With other words: the parameter value is required, the parameter name (= the number) is optional; it cannot be required and not even suggested but it becomes necessary (another thing than the un/requiredness in the sense of template documentation!) when (and only when) the parameter value string contains a "free equal sign" (an equal sign outside of another template).
  The positional number is also necessary when positional parameters are specified outside of their positional order, e.g. |2= |1= |3=
