nothing else, they must be distinguished one from the other.  This is done by looking at their (required) title
parameters:
	título – Spanish
	titolo – Italian 

<funct_t> is a k/v table where k is the ISO 639-1 language code (es: Spanish; it: Italian) and v is the matching
funtion that handles this {{cita news}}, {{cita libro}}, or {{cita web}} template

it.wiki supports positional parameters for <url> ({{{1}}}) and <title> ({{{2}}}); because it is necessary to use
the |title= equivalent to determine which function to call, the it.wiki positional parameters are not supported.
