A template intended to aid the creation of lists which are strings of items separated by a "divider" or "separator" character. The divider/separator character used here is the <small> bullet (•) as it seems less obtrusive than its full-size version (•) or the vertical-line ( | ) – which resembles the uppercase letter "I", lowercase "l" or the upright parts of "h", "k", etc – but more effective than the middot (·), especially in smaller font sizes. The character is preceded by a non-breaking space ( ) so the template may be used as shown below (i.e. suffixed to each item) to prevent the character being linewrapped the starts of lines, thereby compromising the template's appearance.
